Mikhail Antonov commented on HBASE-13103: ----------------------------------------- Online - you mean table-wise, or region-wise? I would think, this might work in 2 steps: - command runs and generates "reshaping plan", which is series or split/merge commands recommended. Then they could be either confirmed by admin (and pushed to execution), or exported as a script for further review? > [ergonomics] add shell,API to "reshape" a table > ----------------------------------------------- > > Key: HBASE-13103 > URL: https://issues.apache.org/jira/browse/HBASE-13103 > Project: HBase > Issue Type: Brainstorming > Components: Usability > Reporter: Nick Dimiduk > > Often enough, folks miss-judge split points or otherwise end up with a > suboptimal number of regions. We should have an automated, reliable way to > "reshape" or "balance" a table's region boundaries. This would be for tables > that contain existing data. This might look like: > {noformat} > Admin#reshapeTable(TableName, int numSplits); > {noformat} > or from the shell: > {noformat} > > reshape TABLE, numSplits > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
