RPC Edge Smart Routing

We are continuously improving our RPC Edge and the latest update is out!

Dynamic Method Based Scoring and Routing for RPC Edge

We implemented a modular scoring strategy to choose the most performant node for the requests. Edge RPC uses method-based scoring and picks the dominant method within a batch. It also supports scoring and retrying JSON RPC server errors and fails over to other nodes if there is a problem.

Edge RPC will know itself how to choose the best upstream node with 99.9% probability. This change will improve error rate, latency and data accuracy and will only improve over time.

First tests are already showing improved latency by 20%!

Error Handling and Logging Updates

We improved Edge RPC's error handling to better follow the JSON RPC spec. RPC errors are now included in the response body and the Edge RPC always returns HTTP 200 status.

Improved internal metrics and logging around Edge RPC failovers and incomplete responses.

Deprecations
Removed support for deprecated Mumbai RPC.

We will start to roll out the Edge RPC scoring method update incrementally and continue to prioritize data correctness and speed.
