Use the following guidelines when you share partitioned Lookup caches:
Lookup transformations can share a partitioned cache if the transformations meet the following conditions:
The cache structures are identical. The lookup/output ports for the first shared transformation must match the lookup/output ports for the subsequent transformations.
The transformations have the same lookup conditions, and the lookup condition columns are in the same order.
You cannot share a partitioned cache with a non-partitioned cache.
When you share Lookup caches across target load order groups, you must configure the target load order groups with the same number of partitions.
If the Integration Service detects a mismatch between Lookup transformations sharing an unnamed cache, it rebuilds the cache files.
If the Integration Service detects a mismatch between Lookup transformations sharing a named cache, it fails the session.
