peformance issue

Hi,

We are facing this issue.

If we copy 10GB of data from Table A to Table B, Table B supposed to have 10GB size however it is allocating almost 1.6 times of parent table(so Table B is having 18GB).

We tried below solution :

Before table creation & load, we set the parameter ‘set option public.minimize_storage = ON.

Direct load instead table creation and then load ‘select * into Table B from Table A’.

Rebuild the system index on individual table (sp_iqrebuildindex ‘gateway.Table B’, ‘index index_name’)

Can anyone help us.

Regards,
