pawg5

a P.A.W.G rub pogreb distributed key/value store using raft for concensus with a redis compatible API

based off of kvnode and bitraft (See LICENSE.old and LICENSE.prologic)

• redis compatible API
• pogreb disk-based storage
• Raft support with finn commands
• compatible with existing Redis clients (probably?)

works like you'd expect prolly

SET key value
GET key
DEL key [key ...]
KEYS pattern

RAFTSNAPSHOT

this will creates a new snapshot in the data/snapshots directory. Each snapshot contains two files, meta.json and state.bin. the state file is the database in a compressed format. The meta file is details about the state including the term, index, crc, and size.

ideally you call RAFTSNAPSHOT and then store the state.bin on some other server like S3.

To restore:

• create a new raft cluster
• download the state.bin snapshot
• pipe the commands using the pawg5 --parse-snapshot and redis-cli --pipe commands

Example:

pawg5 --parse-snapshot state.bin | redis-cli -h 10.0.1.5 -p 4920 --pipe

this will execute all of the state.bin commands on the leader at 10.0.1.5:4920

for information on the redis-cli --pipe command see Redis Mass Insert.
