Review Comment:
The JDBC max batch size may not be equal to Thrift max message size. So the
consumers of these events may get thrift max message limit error if stats are
stored in each of these partitions. So this is a bottle-neck to store the
entire partition object. Can we do something else to satisfy the replication
issue and also at the same time to bring down the size of serialized object?
