Nim-RocksDB

Build Status (Travis) Windows build status (Appveyor) License: Apache License: MIT Stability: experimental

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.

Requirements

A RocksDB installation that provides librocksdb.so. This means that on Debian, and possibly on other Linux distros, you need "librocksdb-dev", not just a versioned "librocksdbX.Y" package that only provides librocksdb.so.X.Y.Z.

Usage

See simple_example

Static linking

To statically link librocksdb, 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.

Building Windows DLLs

Prerequisites:

  • Windows 7 or newer
  • Git
  • Visual Studio 2015 Update 3 or greater with the English language pack

To build RocksDB for Windows, run the following:

.\scripts\build_dlls_windows.bat

After the build completes the built RocksDB DLLs will be located in the build directory.
