netty: The optimization of applying for a minimum of 4096 off-heap memory per request has no effect in non-unaryRequest mode #11719
Description
ClientCallImpl:
MessageFramer:
NettyWritableBufferAllocator:
In non-unaryRequest mode, 4096 bytes of off-heap memory will be re-applied for each message
If you send small packet requests frequently (for example, 100 bytes each time), a lot of external memory will be wasted, and this 4096 optimization logic will not take effect.
