Nim-RocksDB
A Nim wrapper for Facebook's RocksDB, a persistent key-value store for Flash and RAM Storage.
Current status
Nim-RocksDB provides a wrapper for the low-level functions in the librocksdb c library.
Installation
Nim-RocksDB requires Nim and the Nimble package manager. For Windows you will need Visual Studio 2015 Update 3 or greater with the English language pack.
To get started run:
nimble install
This will download and install the RocksDB dynamic libraries for your platform and copy them into the build/ directory of the project. When including this library in your application you may want to copy these libraries into another location or set the LD_LIBRARY_PATH environment variable (DYLD_LIBRARY_PATH on MacOS, PATH on Windows) to include the build/ directory so that your application can find them on startup.
Alternatively you can use the rocksdb_static_linking flag to statically link the library into your application.
Static linking
To build the RocksDB static libraries run:
./scripts/build_static_deps.sh
To statically link RocksDB, you would do something like:
nim c -d:rocksdb_static_linking --threads:on your_program.nim
See the config.nims file which contains the static linking configuration which is switched on with the rocksdb_static_linking flag. Note that static linking is currently not supported on windows.
Usage
See simple_example
