how to monitor changes in a table when there is huge amount od data

Chưa có ai nhận issue này.

Hi,
I used Changes(Table) to init changes, and there are nearly 150,000 records in a table, I just changed one record.I used setStartPointNow() and setEndPointNow() to monitor the changes. when I tried to find what changed in the table, changes.getChangeList() went into an endless loop.
Is there a performance bottleneck about the amount of records in a table.

Testcase run as the following pic:

Start by reproducing the testcase shown in the issue: initialize Changes(Table) for a table with nearly 150,000 records, call setStartPointNow() and setEndPointNow(), then run changes.getChangeList(). Determine whether the call completes after changing one record and document the observed performance or endless-loop behavior as the completion criterion.
