[jira] [Updated] (IGNITE-15755) Unable to clear raft log on raft
node stop in jraft
[ https://issues.apache.org/jira/browse/IGNITE-15755?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
