Types of NETEZZA Planners -



Types of NETEZZA Planners -

what types of planners utilize in netezza , use? eg: facteral_planner

can explain or please provide link know this.

i found an unofficial blog post mentions:

the fact relationship (factrel) planner, the snowflake planner, the star planner.

here's link 1 document entitled determining fact relations fact relation planner , snowflake planner ibm website won't allow me view after logging in client id. may have more luck. title suggests factrel planner uses 1 algorithm (absolute table size) guessing fact tables while snowflake planner uses different method (size relative other tables).

i can't find relevant snowflake planner or star planner in of official documents or training documents have. searches snowflake or star homecoming things schemas rather planners.
