> Advanced heuristics for historical rebalance
> --------------------------------------------
>
> Key: IGNITE-13253
> URL: https://issues.apache.org/jira/browse/IGNITE-13253
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Assignee: Ivan Rakov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Before, cluster detects partitions that have not to rebalance by history, by
> them size. This threshold might be set through a system property
> IGNITE_PDS_WAL_REBALANCE_THRESHOLD. But it is not fair deciding which
> partitions will be rebalanced by WAL only by them size. WAL can have much
> more records than size of a partition (many update by one key) and that
> rebalance required more data than full transferring by network.
> Need to implement a heuristic, that might to estimate data size.
