# fastcache - fast thread-safe inmemory cache for big number of entries in Go
|
||||
|
||||
### Features
|
||||
|
||||
* Fast. Performance scales on multi-core CPUs. See benchmark results below.
|
||||
* Thread-safe. Concurrent goroutines may read and write into a single
|
||||
cache instance.
|
||||
* The fastcache is designed for storing big number of entries without
|
||||
[GC overhead](https://syslog.ravelin.com/further-dangers-of-large-heaps-in-go-7a267b57d487).
|
||||
* Fastcache automatically evicts old entries when reaching the maximum cache size
|
||||
set on its creation.
|
||||
* [Simple API](http://godoc.org/github.com/VictoriaMetrics/fastcache).
|
||||
* Simple source code.
|
||||
* Cache may be [saved to file](https://godoc.org/github.com/VictoriaMetrics/fastcache#Cache.SaveToFile)
|
||||
and [loaded from file](https://godoc.org/github.com/VictoriaMetrics/fastcache#LoadFromFile).
|
||||
* Works on [Google AppEngine](https://cloud.google.com/appengine/docs/go/).
|
||||
|
||||
|
||||
### Benchmarks
|
||||
|
||||
`Fastcache` performance is compared with [BigCache](https://github.com/allegro/bigcache), standard Go map
|
||||
and [sync.Map](https://golang.org/pkg/sync/#Map).
|
||||

|
||||
```
|
||||
|
||||
`MB/s` column here actually means `millions of operations per second`.
|
||||
As you can see, `fastcache` is faster than the `BigCache` in all the cases.
|
||||
`fastcache` is faster than the standard Go map and `sync.Map` on workloads
|
||||
with inserts.
|
||||
|
||||
|
||||
### Limitations
|
||||
|
||||
* Keys and values must be byte slices. Other types must be marshaled before
|
||||
storing them in the cache.
|
||||
* Big entries with sizes exceeding 64KB must be stored via [distinct API](http://godoc.org/github.com/VictoriaMetrics/fastcache#Cache.SetBig).
|
||||
* There is no cache expiration. Entries are evicted from the cache only
|
||||
on cache size overflow. Entry deadline may be stored inside the value in order
|
||||
to implement cache expiration.
|
||||
|
||||
|
||||
### Architecture details
|
||||
|
||||
The cache uses ideas from [BigCache](https://github.com/allegro/bigcache):
|
||||
|
||||
* The cache consists of many buckets, each with its own lock.
|
||||
This helps scaling the performance on multi-core CPUs, since multiple
|
||||
CPUs may concurrently access distinct buckets.
|
||||
* Each bucket consists of a `hash(key) -> (key, value) position` map
|
||||
and 64KB-sized byte slices (chunks) holding encoded `(key, value)` entries.
|
||||
Each bucket contains only `O(chunksCount)` pointers. For instance, 64GB cache
|
||||
would contain ~1M pointers, while similarly-sized `map[string][]byte`
|
||||
would contain ~1B pointers for short keys and values. This would lead to
|
||||
[huge GC overhead](https://syslog.ravelin.com/further-dangers-of-large-heaps-in-go-7a267b57d487).
|
||||
|
||||
64KB-sized chunks reduce memory fragmentation and the total memory usage comparing
|
||||
to a single big chunk per bucket.
|
||||
Chunks are allocated off-heap if possible. This reduces total memory usage because
|
||||
GC collects unused memory more frequently without the need in `GOGC` tweaking.
|
||||
|
||||
|
||||
### Users
|
||||
|
||||
* `Fastcache` has been extracted from [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics) sources.
|
||||
See [this article](https://medium.com/devopslinks/victoriametrics-creating-the-best-remote-storage-for-prometheus-5d92d66787ac)
|
||||
for more info about `VictoriaMetrics`.
|
||||
|
||||
|
||||
### FAQ
|
||||
|
||||
#### What is the difference between `fastcache` and other similar caches like [BigCache](https://github.com/allegro/bigcache) or [FreeCache](https://github.com/coocood/freecache)?
|
||||
|
||||
* `Fastcache` is faster. See benchmark results above.
|
||||
* `Fastcache` uses less memory due to lower heap fragmentation. This allows
|
||||
saving many GBs of memory on multi-GB caches.
|
||||
* `Fastcache` API [is simpler](http://godoc.org/github.com/VictoriaMetrics/fastcache).
|
||||
The API is designed to be used in zero-allocation mode.
|
||||
|
||||
|
||||
#### Why `fastcache` doesn't support cache expiration?
|
||||
|
||||
Because we don't need cache expiration in [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics).
|
||||
Cached entries inside `VictoriaMetrics` never expire. They are automatically evicted on cache size overflow.
|
||||
|
||||
It is easy to implement cache expiration on top of `fastcache` by caching values
|
||||
with marshaled deadlines and verifying deadlines after reading these values
|
||||
from the cache.
|
||||
|
||||
|
||||
#### Why `fastcache` doesn't support advanced features such as [thundering herd protection](https://en.wikipedia.org/wiki/Thundering_herd_problem) or callbacks on entries' eviction?
|
||||
|
||||
Because these features would complicate the code and would make it slower.
|
||||
`Fastcache` source code is simple - just copy-paste it and implement the feature you want
|
||||
on top of it.

# BigCache [](https://travis-ci.org/allegro/bigcache) [](https://coveralls.io/github/allegro/bigcache?branch=master) [](https://godoc.org/github.com/allegro/bigcache) [](https://goreportcard.com/report/github.com/allegro/bigcache)
|
||||
|
||||
Fast, concurrent, evicting in-memory cache written to keep big number of entries without impact on performance.
|
||||
BigCache keeps entries on heap but omits GC for them. To achieve that operations on bytes arrays take place,
|
||||
therefore entries (de)serialization in front of the cache will be needed in most use cases.
|
||||
|
||||
## Usage
|
||||
|
||||
### Simple initialization
|
||||
|
||||
```go
|
||||
import "github.com/allegro/bigcache"
|
||||
|
||||
cache, _ := bigcache.NewBigCache(bigcache.DefaultConfig(10 * time.Minute))
|
||||
|
||||
cache.Set("my-unique-key", []byte("value"))
|
||||
|
||||
entry, _ := cache.Get("my-unique-key")
|
||||
fmt.Println(string(entry))
|
||||
```
|
||||
|
||||
### Custom initialization
|
||||
|
||||
When cache load can be predicted in advance then it is better to use custom initialization because additional memory
|
||||
allocation can be avoided in that way.
|
||||
|
||||
```go
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/allegro/bigcache"
|
||||
)
|
||||
|
||||
config := bigcache.Config {
|
||||
// number of shards (must be a power of 2)
|
||||
Shards: 1024,
|
||||
// time after which entry can be evicted
|
||||
LifeWindow: 10 * time.Minute,
|
||||
// rps * lifeWindow, used only in initial memory allocation
|
||||
MaxEntriesInWindow: 1000 * 10 * 60,
|
||||
// max entry size in bytes, used only in initial memory allocation
|
||||
MaxEntrySize: 500,
|
||||
// prints information about additional memory allocation
|
||||
Verbose: true,
|
||||
// cache will not allocate more memory than this limit, value in MB
|
||||
// if value is reached then the oldest entries can be overridden for the new ones
|
||||
// 0 value means no size limit
|
||||
HardMaxCacheSize: 8192,
|
||||
// callback fired when the oldest entry is removed because of its expiration time or no space left
|
||||
// for the new entry, or because delete was called. A bitmask representing the reason will be returned.
|
||||
// Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
|
||||
OnRemove: nil,
|
||||
// OnRemoveWithReason is a callback fired when the oldest entry is removed because of its expiration time or no space left
|
||||
// for the new entry, or because delete was called. A constant representing the reason will be passed through.
|
||||
// Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
|
||||
// Ignored if OnRemove is specified.
|
||||
OnRemoveWithReason: nil,
|
||||
}
|
||||
|
||||
cache, initErr := bigcache.NewBigCache(config)
|
||||
if initErr != nil {
|
||||
log.Fatal(initErr)
|
||||
}
|
||||
|
||||
cache.Set("my-unique-key", []byte("value"))
|
||||
|
||||
if entry, err := cache.Get("my-unique-key"); err == nil {
|
||||
fmt.Println(string(entry))
|
||||
}
|
||||
```
|
||||
|
||||
## Benchmarks
|
||||
|
||||
Three caches were compared: bigcache, [freecache](https://github.com/coocood/freecache) and map.
|
||||
Benchmark tests were made using an i7-6700K with 32GB of RAM on Windows 10.
|
||||
|
||||
### Writes and reads
|
||||
|
||||
```bash
|
||||
cd caches_bench; go test -bench=. -benchtime=10s ./... -timeout 30m
|
||||
|
||||
BenchmarkMapSet-8 3000000 569 ns/op 202 B/op 3 allocs/op
|
||||
BenchmarkConcurrentMapSet-8 1000000 1592 ns/op 347 B/op 8 allocs/op
|
||||
BenchmarkFreeCacheSet-8 3000000 775 ns/op 355 B/op 2 allocs/op
|
||||
BenchmarkBigCacheSet-8 3000000 640 ns/op 303 B/op 2 allocs/op
|
||||
BenchmarkMapGet-8 5000000 407 ns/op 24 B/op 1 allocs/op
|
||||
BenchmarkConcurrentMapGet-8 3000000 558 ns/op 24 B/op 2 allocs/op
|
||||
BenchmarkFreeCacheGet-8 2000000 682 ns/op 136 B/op 2 allocs/op
|
||||
BenchmarkBigCacheGet-8 3000000 512 ns/op 152 B/op 4 allocs/op
|
||||
BenchmarkBigCacheSetParallel-8 10000000 225 ns/op 313 B/op 3 allocs/op
|
||||
BenchmarkFreeCacheSetParallel-8 10000000 218 ns/op 341 B/op 3 allocs/op
|
||||
BenchmarkConcurrentMapSetParallel-8 5000000 318 ns/op 200 B/op 6 allocs/op
|
||||
BenchmarkBigCacheGetParallel-8 20000000 178 ns/op 152 B/op 4 allocs/op
|
||||
BenchmarkFreeCacheGetParallel-8 20000000 295 ns/op 136 B/op 3 allocs/op
|
||||
BenchmarkConcurrentMapGetParallel-8 10000000 237 ns/op 24 B/op 2 allocs/op
|
||||
```
|
||||
|
||||
Writes and reads in bigcache are faster than in freecache.
|
||||
Writes to map are the slowest.
|
||||
|
||||
### GC pause time
|
||||
|
||||
```bash
|
||||
cd caches_bench; go run caches_gc_overhead_comparison.go
|
||||
|
||||
Number of entries: 20000000
|
||||
GC pause for bigcache: 5.8658ms
|
||||
GC pause for freecache: 32.4341ms
|
||||
GC pause for map: 52.9661ms
|
||||
```
|
||||
|
||||
Test shows how long are the GC pauses for caches filled with 20mln of entries.
|
||||
Bigcache and freecache have very similar GC pause time.
|
||||
It is clear that both reduce GC overhead in contrast to map
|
||||
which GC pause time took more than 10 seconds.
|
||||
|
||||
## How it works
|
||||
|
||||
BigCache relies on optimization presented in 1.5 version of Go ([issue-9477](https://github.com/golang/go/issues/9477)).
|
||||
This optimization states that if map without pointers in keys and values is used then GC will omit its content.
|
||||
Therefore BigCache uses `map[uint64]uint32` where keys are hashed and values are offsets of entries.
|
||||
|
||||
Entries are kept in bytes array, to omit GC again.
|
||||
Bytes array size can grow to gigabytes without impact on performance
|
||||
because GC will only see single pointer to it.
|
||||
|
||||
## Bigcache vs Freecache
|
||||
|
||||
Both caches provide the same core features but they reduce GC overhead in different ways.
|
||||
Bigcache relies on `map[uint64]uint32`, freecache implements its own mapping built on
|
||||
slices to reduce number of pointers.
|
||||
|
||||
Results from benchmark tests are presented above.
|
||||
One of the advantage of bigcache over freecache is that you don’t need to know
|
||||
the size of the cache in advance, because when bigcache is full,
|
||||
it can allocate additional memory for new entries instead of
|
||||
overwriting existing ones as freecache does currently.
|
||||
However hard max size in bigcache also can be set, check [HardMaxCacheSize](https://godoc.org/github.com/allegro/bigcache#Config).
|
||||
|
||||
## HTTP Server
|
||||
|
||||
This package also includes an easily deployable HTTP implementation of BigCache, which can be found in the [server](/server) package.

||||

"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|

represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain

|
||||
this License, each Contributor hereby grants to You a perpetual,

||||
copyright license to reproduce, prepare Derivative Works of,
|

Work and such Derivative Works in Source or Object form.
|

where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|

4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||

"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

# Go sigar [](https://travis-ci.org/elastic/gosigar) [](https://ci.appveyor.com/project/elastic-beats/gosigar/branch/master)
|
||||
|
||||
|
||||
## Overview
|
||||
|
||||
Go sigar is a golang implementation of the
|
||||
[sigar API](https://github.com/hyperic/sigar). The Go version of
|
||||
sigar has a very similar interface, but is being written from scratch
|
||||
in pure go/cgo, rather than cgo bindings for libsigar.
|
||||
|
||||
## Test drive
|
||||
|
||||
$ go get github.com/elastic/gosigar
|
||||
$ cd $GOPATH/src/github.com/elastic/gosigar/examples/ps
|
||||
$ go build
|
||||
$ ./ps
|
||||
|
||||
## Supported platforms
|
||||
|
||||
The features vary by operating system.
|
||||
|
||||

## OS Specific Notes
|
||||
|
||||
### FreeBSD
|
||||
|
||||
Mount both `linprocfs` and `procfs` for compatability. Consider adding these
|
||||
mounts to your `/etc/fstab` file so they are mounted automatically at boot.
|
||||
|
||||
```
|
||||
sudo mount -t procfs proc /proc
|
||||
sudo mkdir -p /compat/linux/proc
|
||||
sudo mount -t linprocfs /dev/null /compat/linux/proc
|
||||
```

How to Apply These Terms to Your New Programs
|

|

If you develop a new program, and you want it to be of the greatest

|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.

| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |

It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However, it also accepts Solidity source files, making development much more streamlined.

|
||||
| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
