Andrew Kryczka 93f69cb93a use bottommost compression when base level is bottommost ... Summary: The previous compression type selection caused unexpected behavior when the base level was also the bottommost level. The following sequence of events could happen: - full compaction generates files with `bottommost_compression` type - now base level is bottommost level since all files are in the same level - any compaction causes files to be rewritten `compression_per_level` type since bottommost compression didn't apply to base level I changed the code to make bottommost compression apply to base level.
