------------------------------------------------------------
The second scenario is the streaming computing scenario (Streaming Computing)

This kind of scenario has the following requirements:

1. Online services are updated in real time and require CDC components to synchronize the updates to the analysis library.

2. The analytics library needs to be real-time and able to synchronize changes in online business data.

3. The analysis library provides an SQL interface for analyzing queries.

According to the above requirements, it is an excellent choice to be able to simultaneously support high-concurrent updates and spot checks on the application side, and to be able to synchronously update to the TiDB database that supports analysis queries.
