## Description This PR optimize memory footprint of RPC (i.e., memory used by serde).
Serde uses up more than 10x memory to deserialize a json message when using `#[serde(flatten)]` and `#[serde(tag = "request"]`. In our case, we cannot handle more than 2M message because serde will allocation more than 100M bytes memory. The root cause is still unknown. ## Type of change (select or add applied and delete the others) - [x] Breaking change (fix or feature that would cause existing functionality to not work as expected) ## How has this been tested? CI tests. ## Checklist - [x] Fork the repo and create your branch from `master`. - [x] If you've added code that should be tested, add tests. - [x] If you've changed APIs, update the documentation. - [x] Ensure the tests pass (see CI results). - [x] Make sure your code lints/format.
