> Need to support truncate table for replication. Key points to note.
> 1. For non-partitioned table, truncate table will remove all the rows from the table.
> 2. For partitioned tables, need to consider how truncate behaves if truncate a partition
or the whole table.
> 3. Bootstrap load with truncate table must work as it is just loadTable/loadPartition
with empty dataset.
> 4. It is suggested to re-use the alter table/alter partition events to handle truncate.
