Intelligent Batch Packet Broadcasting

[nik-suri]

Summary

Intelligently compute number of packets to batch broadcast based on max_gas.

Problem Definition

It looks like when there are a lot of pending packets the relayer will pull and try to broadcast up to 50 packets at a time. However, if the max_gas in the config is lower than the gas requirement to broadcast all these packets, the transaction will fail and the relayer doesn’t seem to relay those pending packets, so they’re effectively stuck.

Proposal

It’s not the greatest fix to have to adjust the max_gas requirement — is there some config for max packets to relay at once? Not sure if, after the batch broadcast fails, hermes then tries to relay the packets 1 by 1? A helpful feature that still does batch broadcasting could calculate the proper number of packets to batch broadcast that’s within the max_gas config and relay that amount.

Acceptance Criteria

Either a feature is implemented to support this, or there is a workaround we don't yet know of!
