Review comment:
Both `PartitionsSpec` and `indexSpec` can be helpful in determining the
cause of query performance issue. We will also want to know what segments auto
compaction will compact as both of those Spec determine that. 'indexSpec' can
also impact query performance (see shape shifting PR).
CompactionState is a small json and is already stored in memory as part of
the DataSegment. We are also returning the shardSpec so this should not be a
problem.
