> 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
> Assignee: Semen Boikov
> 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).
