## 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.
