Readme

levigo

levigo is a Go wrapper for RocksDB.

The API has been godoc'ed and is available on the web.

Questions answered at golang-nuts@googlegroups.com.

Building

You'll need the shared library build of RocksDB installed on your machine. The current RocksDB will build it by default.

Now, if you build RocksDB and put the shared library and headers in one of the standard places for your OS, you'll be able to simply run:

go get github.com/mikefaille/rocksdb-go

But, suppose you put the shared RocksDB library somewhere weird like /path/to/lib and the headers were installed in /path/to/include. To install levigo remotely, you'll run:

CGO_CFLAGS="-I/path/to/rocksdb/include" CGO_LDFLAGS="-L/path/to/rocksdb/lib" go get github.com/mikefaille/rocksdb-go

and there you go.

In order to build with snappy, you'll have to explicitly add "-lsnappy" to the CGO_LDFLAGS. Supposing that both snappy and rocksdb are in weird places, you'll run something like:

CGO_CFLAGS="-I/path/to/rocksdb/include -I/path/to/snappy/include"
CGO_LDFLAGS="-L/path/to/rocksdb/lib -L/path/to/snappy/lib -lsnappy" go get github.com/mikefaille/rocksdb-go

(and make sure the -lsnappy is after the snappy library path!).

Of course, these same rules apply when doing go build, as well.

Caveats

Comparators and WriteBatch iterators must be written in C in your own library. This seems like a pain in the ass, but remember that you'll have the RocksDB C API available to your in your client package when you import levigo.

An example of writing your own Comparator can be found in https://github.com/mikefaille/rocksdb-go/tree/master/examples.
