Hi Dmitry, You can try to create additional table with only row ID and field for join. So, you will be able to make joins, but you will need to retrieve detailed data from external store manually.
To speed up external store lookups, you can create one more cache with eviction policy backed with external store. Also, you can configure cache interceptor to automatically substitute values from external store on basic get\put operations. However, this will not work for Scan and SQL queries.
