sql - Reading from transaction tables -



sql - Reading from transaction tables -

i have 2 tables need refreshed every 1 hour. 1 table truncate load , other 1 incremental load. total process takes around 30 seconds complete. there couple of applications hitting these tables on continuous basis. can't have applications blank info @ moment. thought done operations on these table doesn't impact output on ui (including truncate/load)? thinking of creating mv on these tables, improve approach?

convert truncate delete , create whole process 1 transaction. if current process takes 30 seconds overhead of deleting , conventional inserts shouldn't bad.
