persistent cache is used when u r mapping contains multiple dimensions table, which is used in several times. if you use persistence cache all the index files and data files are stored in memory. when the integration serviece second time calls the same lookup table it wioll fetch the data from the memory cache files instead of re-creating the index and data cache files. we can use the same cache by using one name prefix of the lookup properties.
to use use persistence cache we can divide them in to two types.
1) names persistence cache
2) un named persistence cache.

1) named persistence cache: we can use the same persistence cache between several mappings.
2)un named persistence cache we can use the same cache with in the mapping only.

What is the reusable transformation?
