Prioritized mempool follow-ups #9077

@thanethomson

Description

@thanethomson
  • spec: priority mempool specification #9310
    - Link to existing ADR when prioritized mempool was introduced.
  • Performance and stability are at least as good as the mempool in v0.34 (no regression).
  • Prioritized mempool implemented and tested according to the specification.
    • Ability to provide priority to transactions in CheckTx responses, which deliver transactions to the application in priority-based order.
  • Transactions are still gossiped in FIFO order.
  • We have a clear answer to the question as to whether we need the prioritized mempool when ABCI++ lands
    • If not we need to remove the Priority field from CheckTx. This impacts the release of ABCI++.
