Edward Bortnikov commented on HBASE-16417:
------------------------------------------
Notes to the suggested definition:
1. Speculative scans have been eliminated as merge trigger - turn to be to
costly. With option 3 (compact_data), the user takes the responsibility for
what he's doing.
2. The default implementation for immutable sorted index is CellArrayMap (an
array of references to Cell objects). The CellChunkMap implementation embeds
the Cell objects into the sorted index array, and saves some space by doing so.
The index implementation is orthogonal to in-memory flush policy. The
CellChunkMap index only works with MSLAB data storage. The use cases for it are
TBD. For example, if it is only planned to work with off-heap data, no separate
configuration is required. Let's follow this up separately on HBase-16421.
