Neynar

If you want to subscribe to our Kafka data pipeline but don't want to pay for all of the messages you're not interested in, such as reactions, now you don't have to. In addition to our aggregated offering, we have broken out farcaster events into separate Kafka topics for users, casts, reactions, follows, and signers to save you $ and bandwidth. Reach out to @rish if you're interested!

> how does this compare to the gRPC event stream on snapchain nodes?

every message on neynar's streaming product is fully hydrated with the exact same objects (user, cast, etc.) that power our API. 
- a user object contains neynar user score, follow counts, etc.
- a cast object contains channel metadata, embedded cast data, etc.

the snapchain gRPC stream is better if you're looking for low-latency, raw protocol messages. it has added implemetation complexity to deal with multiple shards on the snapchain.
