/**
* Current OceanBase connector uses timestamp (in seconds) to mark the offset during the
* transition from {@code SNAPSHOT} to {@code STREAMING} mode. Thus, if some snapshot inserting
* events are too close to the transitioning offset, snapshot inserting events might be emitted
* multiple times. <br>
* This could be safely removed after switching to incremental snapshot framework which provides
* Exactly-once guarantee.
