--------------------------------
Hi, [~srichter] After going through the doc of this feature, I think it is a
good improvement to eliminate the usage of checkpoint lock. Before I was
confused by the checkpoint lock used in processing time trigger. And i am
interested on this issue, can i do a favour to work on this issue, thanks.
