You need to do a little prep on the data that is the source of the enrichment.
Abritraty joins are not supported, and large-scale arbitrary joins are not on the near-term roadmap.
However, I expect that in the near future, additional capabilities will be available, such as lookup, which will allow enriching (joining) a large index with an arbitrary smaller index or file, etc... Stay tuned for that.
