### The flow chart is as follow:  1. master meta: receive create dup table request and mark current `max_plog_commit_decree` as start plog point 2. master meta: init the dup status as `DS_PREPARE`, which means master replica need prepare latest_checkpoint for duplicating 3. master replica: generate latest checkpoint , which require `laster_durable_decee >= max_plog_commit_decree` 4. master replica: update all checkpoint has been prepared and response master meta 5. master meta: change to `DS_APP`, which means all checkpoints have prepared and follower can duplicate it 6. master meta: send create table request to follower meta, and require the table init with `master replica checkpoint`(like restore progress which init table with `backup replica checkpoint`) 7. follower meta: create dup table with dup info 8. follower replica: start open or init replica 9. follower replica: duplicate checkpoint from master replica before init replica, and load replica using duplicated data 10. master meta: check the follower table if create completed periodically 11. master meta: if completed, change to `DS_LOG`, which means master replica can send plog data to follower table 12. master replica: start pipeline to batch send plog data. -- This is an automated message from the Apache Git Service.
