[v8.4.2] How doesn inheritance work?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all.

I'd like to know how is inheritance handled when the number of child
tables grows and
I'm accessing (actually SELECTing from) the master, possibly with
contraint exclusion enabled.

How does grow then planner time and  the query execution time for such
queries when
the number of children increases? Is it linear or what?

MTIA.
