Yes, for sure. They are both distributed object stores and share inspiration from the Linda/tuplespace lineage, as well as relational and document databases in FaunaDB's case.

FaunaDB supports function execution in the database, if the functions are written in FQL. It has a much more powerful index system and consistency model than Gemstone/Gemfire/Geode and is designed for synchronous global replication.

However, unlike Geode it is not an in-memory system, so it is not appropriate to use as a cache.

As noted in the writeup, the FaunaDB transaction model uses a unique query expression language. Geode applies a more familiar begin + <operations> + commit / abort approach.

Geode skews towards eventual consistency when connecting geographically dispersed clusters. This means you still get super fast local transactions with batched updates to remote sites.
