Maxim Muzafarov updated IGNITE-11704: ------------------------------------- Labels: rebalance (was: ) > Write tombstones during rebalance to get rid of deferred delete buffer > ---------------------------------------------------------------------- > > Key: IGNITE-11704 > URL: https://issues.apache.org/jira/browse/IGNITE-11704 > Project: Ignite > Issue Type: Improvement > Reporter: Alexey Goncharuk > Priority: Major > Labels: rebalance > > Currently Ignite relies on deferred delete buffer in order to handle > write-remove conflicts during rebalance. Given the limit size of the buffer, > this approach is fundamentally flawed, especially in case when persistence is > enabled. > I suggest to extend the logic of data storage to be able to store key > tombstones - to keep version for deleted entries. The tombstones will be > stored when rebalance is in progress and should be cleaned up when rebalance > is completed. > Later this approach may be used to implement fast partition rebalance based > on merkle trees (in this case, tombstones should be written on an incomplete > baseline). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
