>             Project: HBase
>          Issue Type: Improvement
>    Affects Versions: 1.0.0, 2.0.0
>            Reporter: Andrey Stepachev
>            Assignee: Andrey Stepachev
>            Priority: Minor
>
> Currently meta keeps up to 10 versions of each KV. 
> For big metas it leads to substantial memory overhead and scan slowdowns.
> (see https://issues.apache.org/jira/browse/HBASE-11165 )
> Need to keep reasonable number of versions (suggested value is 3). 
> Even better make that configurable.
