Informix - Problembeschreibung

Problem IT27540 Status: Geschlossen

PERFORMANCE PROBLEM WITH CLIPGETCOUNT ON TIMESERIES COLUMN DEFINED TO
USING ROLLING WINDOW CONTAINERS

Produkt:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problembeschreibung:
Clipgetcount() seems to be much more expensive in execution
terms when used on a timeseries using rolling window storage
compared to a timeseries stored in a single container.

Clipgetcount() seems to have to read every container in the
active window list even though it takes arguments defining the
range needing to be examined, which appears to be much more
expensive then looking at a single container containing a much
larger data set for just the 1 timeseries.
