Hi folks. I have a question about task instances.
Is it possible to delete old task instances that have run successfully? Isn't it trying to backfill missing tasks? I have about 1,500 dags and am getting more dags. There're about 300 thousand of task instances currently. 10,000 tasks instances are made by every day. It'll use 3.6 million rows of mysql table in an year. I have concerns about a table which stores task instances that makes large table which can cause performance degradation. How can I keep the table which stores task instances not to be bloated? Thanks, Yongjun
