Dynamic cache is used to update/insert the records into the
cache during the session run. From there we can
update/target table with the NewLookupRow values returned by
lookup.
If you want to use the same lookup cache in other mappings
also then we will go for Persistent Cache.
The difference is for eg, in the first mapping when we use
dynamic cache, when the session ends, the cache gets deleted
automatically. So to use this cache in other mappings also
check give one option "Persistent Cache".
So when we use this option, the cache in the memory gets
Saved even after session ends. From there we can use that in
other mappings.

If the lookup cache doesnt change between mutiple runs and
if we know that the lookup data doesnt change then we will
go for Persistant cache.
If the loopup cache changes between multiple session runs
and to keep the target table and lookup cache synchronized
we will use dynamic lookup cache .
