What Isolation Levels Does Clustrix Support?

Nick Lamb -

Clustrix supports READ COMMITTED & REPEATABLE READ isolation levels. The default value is REPEATABLE-READ. This can be changed with the tx_isolation variable on a per session or global level.

To change for the session:

sql> set tx_isolation = 'REPEATABLE-READ';

To change the default/global:

sql> set global tx_isolation = 'REPEATABLE-READ';

You can get more information on these modes from our documentation in the Isolation Levels section of the Concurrency Control Documentation.
