Release version 0.22.0 of the Hedera JSON RPC Relay includes several performance optimizations that avoid calling more than necessary the mirror node, in methods such as: eth_getBalance, eth_blockNumber, eth_feeHistory that caches results for a configurable amount of time.
Also HttpClient (Axios) configurations improvements when calling mirror node to avoid stale connections as well as some improvements on the liveness and health checks of infrastructure to avoid unneeded restarts when the load is high.
This release includes some further advancements on eth_subscribe feature, adding configurable support for multiple contracts, IP rate limiting and expanding the overall test coverage for more scenarios.
It also includes some tests fixes that improves the overall CI pipeline process and code review process by including code owners.
