(Updated Oct. 14, 2016, 7:19 a.m.) Review request for hbase. Changes ------- Taking care for transferring the open scan counters to the new MSLAB after the merge Repository: hbase-git Description ------- This is a step toward final compacting memstore that allowes two modes of work: index-compaction and data-compaction. The index-compaction means that when the new segment is pushed into the pipeline, it is flattened and probably merged with old segments in the pipeline. The new merge "feature" induces no data-copy-compaction and no speculative SQM scan. The compacting memstore of the data-compaction type means the usage of the data-copy-compaction.
