Question { 4043 }

what are Lookup caches options? Including persistent caches.

Answer

There are two types of Lookup Cache options -

1. Dynamic cache.
2. Persistent cache

1. dynamic Cache - The Dynamic cache is a property of the
look up which if selected makes other ports of the same
record to be checked as Look up apart from the Look up port.

2. Persistent Cache - persistent cache is something like on
the first run the lookup table values gets into a cache and
is stored on the server's hard disk. Each time the run is
made the values would be looked up from this cache only.

Persistent cache is done only when the lookup has to be
made on same set of values each time.
