geyser: add more slot statuses like FirstShredReceived, CreatedBank #2957

Open fanatid opened 2 weeks ago

fanatid commented 2 weeks ago

Problem

It's not possible to implement a fully compatible Solana/Agave WebSocket (PubSub) replacement based on geyser. We only have access to processed / confirmed / finalized but with WebSocket additionally we have access to FirstShredReceived / Completed CreatedBank / Dead (https://github.com/anza-xyz/agave/blob/v2.0.10/rpc-client-api/src/response.rs#L187-L221). For example in https://github.com/Block-Logic/ping-thing-client we rely on FirstShredReceived to benchmark transaction landing and we would like to switch to geyser based tools.

Proposed Solution

Add more statuses to geyser.

These seems to be some "new" slot status sate. We should be able to support it in Geyser -- will come up with a PR soon.
