Ray Mattingly updated HBASE-29203:
----------------------------------
Issue Type: Improvement (was: Bug)
> There should be a StorefileSize equivalent to the TableSkewCost
> ---------------------------------------------------------------
>
> Key: HBASE-29203
> URL: https://issues.apache.org/jira/browse/HBASE-29203
> Project: HBase
> Issue Type: Improvement
> Components: Balancer
> Affects Versions: 2.7.0
> Reporter: Ray Mattingly
> Assignee: Ray Mattingly
> Priority: Major
>
> We don't want to rely on per-table balancing, but we do want tables to be
> balanced effectively based on their data size. This is because regions are
> variably sized, but 1gb is always 1gb, so, in a well distributed schema, data
> size is a better metric for a region's load than just counting every region
> identically.
> Right now the TableSkewCostFunction is the balancer's mechanism for balancing
> each table somewhat independently within a cluster-wide plan, but it only
> looks at region counts. We could balance more effectively if we had a
> StoreFileTableSkewCost.
