Paul Hauner 661307dce1 Separate committee subscriptions queue (#3508) ... ## Issue Addressed NA ## Proposed Changes As we've seen on Prater, there seems to be a correlation between these messages ``` WARN Not enough time for a discovery search subnet_id: ExactSubnet { subnet_id: SubnetId(19), slot: Slot(3742336) }, service: attestation_service ``` ... and nodes falling 20-30 slots behind the head for short periods. These nodes are running ~20k Prater validators. After running some metrics, I can see that the `network_recv` channel is processing ~250k `AttestationSubscribe` messages per minute. It occurred to me that perhaps the `AttestationSubscribe` messages are "washing out" the `SendRequest` and `SendResponse` messages. In this PR I separate the `AttestationSubscribe` and `SyncCommitteeSubscribe` messages into their own queue so the `tokio::select!` in the `NetworkService` can still process the other messages in the `network_recv` channel without necessarily having to clear all the subscription messages first. ~~I've also added filter to the HTTP API to prevent duplicate subscriptions going to the network service.~~ ## Additional Info - Currently being tested on Prater		2022-08-30 05:47:31 +00:00
