Subj: | | Performance issue after splitting the big table |
|
From: | | rishi.agarwal |
Hi,
We have a table that is very big in size ~ 5TB. For maintenance purpose and also to reduce the loading time by parallel loading, we split the
tables in 6 parts. We created a view doing UNINON ALL on these 6 tables to access the data. But, after splitting the table, queries are running
slow on this view.
Can anyone advise what could be the reason for the same and alternative to handle the situation.
Thanks & Regards
Rishi Agarwal
