---------------------------------------
Summary: Purge logs after snapshot only after all the nodes have
catught up with the index
Key: RATIS-563
URL: https://issues.apache.org/jira/browse/RATIS-563
Project: Ratis
Issue Type: Bug
Components: snapshot
Affects Versions: 0.3.0
Reporter: Mukul Kumar Singh
Leader will purge the snapshot after applying a transaction. A transaction is
applied after a majority has been reached. This means that a slow follower will
request for a transaction which has already been purged and for this
transaction to catchup the leader has to transfer the snapshot. This can be
detrimental for the performance while replicating.
