More interesting things about the Clustered Column store index..

I’ve previously blogged on some interesting things about the clustered column store index or CCSI for short.

I’ve found my CCSI in an internal table.  sys.Column_store_row_groups

Noticed the size_in_byte…NULL

Just for fun, I tried to create a 2nd column store index on the same table. (Non-clustered of course)

So we can’t add a non-clustered column store index (NCCSI) to a table that already has a CCSI.

But can we add two NCCSI to a table? The answer is no, but the UI doesn’t let you get that far.  Its non-selectable.. interesting..

And more digging….
