Subject Read Only Tables
Date Wed, 29 Jul 2015 19:53:49 GMT
Folks,

I have been thinking about read only tables which persist to disk and are
in OLAP workloads. Imagine static dimension table.

I think this will include three things:

1) having new ring buffer to always maintain pages of these tables in
memory for maximum performance.
2) Reducing size of header for tuples for these tables (no need for locks
and all).
3) changing visibility qualification around them.

Thoughts?
