Vladislav Pyatkov updated IGNITE-15755:
---------------------------------------
Description:
h3. Problem
In case of partition reassignment, meta storage reconfiguration or table drop
it's required not only to cleanup data storage but also clear stable raft log.
Currently there's no such method in api.
h3. Possible Solution
[~ascherbakov] suggested updating
{code:java}
org.apache.ignite.raft.jraft.RaftGroupService#shutdown{code}
with {color:#1d1c1d}boolean cleanupState{color} flag
{code:java}
org.apache.ignite.raft.jraft.RaftGroupService#shutdown(boolean
cleanupState){code}
RAFT initializes three different storage for a group:
{code:java}
nodeOptions.setLogUri(serverDataPath.resolve("logs").toString());
nodeOptions.setRaftMetaUri(serverDataPath.resolve("meta").toString());
nodeOptions.setSnapshotUri(serverDataPath.resolve("snapshot").toString())
{code}
when the RAFT group is dropping from node (assignment changed or table is
dropped) all those directories have to remove from disk.
Implementation requited:
# Implement a method _LogStorage#destroy_, the method will clear storage folder.
# Add an invocation of this method to API. It might add a _destroy_ flag to
method RaftServer#stopRaftGroup or add another one method.
