Questions :I have three tables which contains around 20millions of records. I am planning to update these three tables for all records. Could you suggest me best approaches to meet this, please?
Ans:
1.I think disable index before update ? And autovacuum off,arhvive off if possible.
2.Increase the check point time out
Increase shared buffer or wall beffer if archive enable.
3.Check any parallel option is there.
