Uncached lookup: The informatica server doesnot build a
cache for temporary starage of data. Wenever it need to
refer to the look up table, it scans the source directly.
Dynamic Cache: The informaatica server builds a cache of
the source wen the workflow runs for the first time and it
updates the cache records dynamically after each row it
loads to the target. Means, if a target row gets updated,
the dynamic cache also gets updated automatically after
that particular row comitted in the target.
or
Dynamic cache - can be configured as connected lookup only.
It does not support lookup on flat file. Can have only
equality operator in lookup condition.
Static cache - can be configured as connected as well as
unconnected lookup. Supports lookup on flatfile. Can have
any relational operator in lookup condition.
