Archive data suggestion

EK9
I have a table contains huge rows of data. Performance issue raised. I am
thinking archive some data so that the table will not be that big. The most
convience way is move it to another table. The problem is: will this solve
my performance problem? or I need to move it to another database to reduce
the database size?

Regards,

Taking a chunk of your data out of a table will certainly improve
performance on queries against that table, if users have to access data
that contains data from both the old and new tables performance will
suffer. THink of it this way, if users are looking for a needle in a
haystack, decreasing the size of the haystack will decrease the length
of time to find the needle.

Whether you put the archive table in the same or another database
does not affect performance for queries. It could reduce time for
backup and restore though.

However, it is far from certain than archiving data is the best way.
Maybe you need to review which indexes you have on the table.
