Review Comment:
   `query` have the higher priority.

partition_column is set, it will be executed  in parallel according to the 
concurrency of tasks.

+
+> This is a simple example of Mysql via Jdbc Sink

Review Comment:
   Please add more information about this example. For example:
   
   **This example defines a SeaTunnel synchronization task that automatically 
generates data through FakeSource and sends it to JDBC Sink. FakeSource 
generates a total of 16 rows of data (`row.num=16`), with each row having two 
fields, name (string type) and age (int type). The final target table is 
`test_table`  will also be 16 rows of data in the table.**
   
   > Before run this job, you need create database `test` and table 
`test_table` in your mysql. And if you have not yet installed and deployed 
SeaTunnel, you need to follow the instructions in [Install 
SeaTunnel](../../start-v2/locally/deployment.md) to install and deploy 
SeaTunnel. And then follow the instructions in [Quick Start With SeaTunnel 
Engine](../../start-v2/locally/quick-start-seatunnel-engine.md) to run this job.

Review Comment:
   Some examples we need to tell the user which options is needed. For example:
   
   **In this case, you need config `database`, `table` and `primary_keys`.**

+## tips
+
+> If partition_column is not set, it will run in single concurrency, and if 
partition_column is set, it will be executed  in parallel according to the 
concurrency of tasks.
+
+## Task Example
+
+### simple:
+
+> This is to access your data source according to your query parameter We can 
use this if we don't have a speed requirement

Review Comment:
   Same as above, we need let user know what does this example do.
