> 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).
> Number of versions configurable via parameter: hbase.meta.versions
