Hi Guys,
I have 2 identical tables each containing 183 mio records.
One of them is compressed and the other isn't.
The compressed table takes up 16 GB in memory the other 55 GB.
If I look in m_cs_columns under compression_type table 1 has different types for each column (RLE,CLUSTERED,INDIRECT,PREFIXED)
and table 2 has compression_type DEFAULT in all columns.
My guess is that the evalutation of compression_type hasnt run. Because the optimization works fine on the first table.
In table "tables" both tables have AUTO_OPTIMIZE_COMPRESSION_ON set to TRUE and are otherwise totally identical.
Is there any way i can initiate this optimization by a command?
Or do you have any other suggestions?
Best Regards
- Rasmus
