commit d1bb19b8f751875472211312c8e810143a7ba4b6
Author: Manuel Ung <mung@fb.com>
Date: Fri Feb 3 11:50:34 2017 -0800
Add cardinality stats to information schema
Summary: This adds cardinality stats to the INFORMATION_SCHEMA.ROCKSDB_INDEX_FILE_MAP table. This is the only missing user collected properties from SST files that we don't expose, which is useful for debugging cardinality bugs.
