h2. *RocketMQ Streams* 

RocketMQ Streams is a lightweight stream processing framework, application 
gains the stream processing ability by depending on RocketMQ Streams as an SDK.

h2. *Task*

The observability needs to be enhanced in the following aspects:
 * The metric of client/processor/thread/state/rocksdb;
 * The topology of streaming process;
 * Mutli-output of metrics;

This task need you to study the implementation details of RocketMQ Streams 
streams, and find out the key indicators in the stream processing process. 
Design and implement a complete set of observability solutions, and finally use 
it to complete runtime problem diagnosis;
