Basho Leveldb

The basho-tuned leveldb embedded database is currently the default storage backend for DVID. During a DVID build, the leveldb code is compiled and linked with the DVID Go language code.

The various leveldb options are set in the basholeveldb driver under the storage package.

The dvid-backup utility assumes a leveldb directory store, takes a snapshot of the immutable files after server shutdown, and rsyncs to a backup location.

So far we have been really pleased with the performance and reliability of this system and commend its developers from the Basho team for their great work and time answering questions.
