    Description

      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.
