If every file group just transfrom to a same name file group. If the small files can not merge ? @lw309637554 1. Yes, the actual strategy can be added easily if we agree on high level change 2. This is to support HBaseIndex, which does not support update for record location 3. yes, you are right. merging strategy cannot be applied to tables that use HBaseIndex. We can still local 'file-level' sorting i.e., sorting records in each data file by specified column so only one block (row group) needs to be read for queries.
