Federate reference blog post & a quick "what's cooking"

This is the reference blog post for Federate, which includes a benchmark.

Currently cooking in Federate:

  • Caching layer. Extremely memory efficient caching. We have exciting preliminary results and expected release in Siren 10.3.
  • Full join support.
  • Connector for remote Elasticsearch clusters. Use remote ES as a datasource (also works with Ingestion) and allow joins across indexes (low scalability if they’re plain ES or efficient if they have the federate plugin).
