Chen Luo updated ASTERIXDB-2776:
--------------------------------
Description: During rebalancing, we upsert a lot of records into the new
dataset, which also produce a lot of log records. However, the transaction log
is never truncated on the metadata node since the rebalance operation itself is
a metadata transaction. (was: During rebalancing, we upsert a lot of records
into the new dataset, which also produce a lot of log records. However, the
transaction log is never truncated because the storage still uses the LSN of
the old dataset.)
