BadWolf Drivers

BadWolf is a temporal graph store loosely modeled after the concepts introduced by the Resource Description Framework (RDF). It presents a flexible storage abstraction, efficient query language, and data-interchange model for representing a directed graph that accommodates the storage and linking of arbitrary objects without the need for a rigid schema.

BadWolf main repository contains the implementation, but no persistent drivers. This repository contains a collection of driver implementations aim to provide, mainly, persistent storage alternatives.

Currently available driver implementations

• bwbolt stores and indexes all triples using the key value store BoltDB.

Building the command line tool

Assumming you have a fully working installation of GO that supports golang modules>

$ cd /to/some/new/folder
$ go install github.com/google/badwolf-drivers/...

These commands should not output anything unless something fails. You can check that the new bw tools contains the new drivers by checking the --driver help flag information. You should see drivers other than VOLATILE

 $ $GOPATH/bin/bw -h
Usage of /usr/local/go/bin/bw:
  -bolt_db_path string
    	The path to the Bolt database to use.
  -bql_channel_size int
    	Internal channel size to use on BQL queries.
  -driver string
    	The storage driver to use {VOLATILE|BWBOLT}. (default "VOLATILE")

For more information about how to use the commands or how the flags work please see the original documentation.

Testing the command line tool

You may always want to run all the test for both repos badwolf and badwolf-drivers to make sure eveything is A-Ok. If the tests fail, you should consider not using the build tool since it may be tainted.
