The `computeAndWriteStatsFile` loaded the whole previous stats file into memory before merging. Now it streams the previous file and merges it with the sorted incremental stats, so only the incremental stats are held in memory. Peak heap growth for an incremental write on a 500k-partition table dropped from ~186 MB to ~33 MB. The existing tests cover the incremental merge and corrupted-file fallback. The new test checks merged output stays sorted by partition. -- This is an automated message from the Apache Git Service.
