Yes joiner transformation has cahches. It joins the data
based on master detail joining condition. It first reads
the master source and stores it in the joiner cache and it
reads the detail source and joins with the data in the
joiner cache based on the master detail joining condition.

Answer / krish
Caching Master Rows
When the Integration Service processes a Joiner
transformation, it reads rows from both sources concurrently
and builds the index and data cache based on the master
rows. The Integration Service then performs the join based
on the detail source data and the cache data.
