> If we insert data into an acid partitioned table from Hive, the generated events will be like open_txn -> alter_partition -> commit_txn.
> In alter_partition event, we will refresh the partition (without refreshing file metadata) because the write id with the partition object in the event > write id of the cached partition. Then, in commit_txn event, we still do the same write id check. However, the write id is still the same, so we end up don't fresh file metadata.
