+
+## Task Example
+
+### simple:
+
+> 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`.**

+
+## Description
+
+Read external data source data through JDBC.
+
+## Supported DataSource list
+
+| datasource | supported versions | driver | url | maven |
+|------------|-----------------------------------------------|--------------------------|---------------------------------------|---------------------------------------------------------------------------|
+| mysql | Depending on your Database dependency version | com.mysql.cj.jdbc.Driver | jdbc:mysql://localhost:3306:3306/test | [Download](https://mvnrepository.com/artifact/mysql/mysql-connector-java) |
+
+## Database dependency
+
+> Please download the support list corresponding to 'Maven' and copy it to the '$SEATNUNNEL_HOME/plugins/jdbc/lib/' working directory<br>
+> For example Mysql datasource: cp mysql-connector-java-xxx.jar $SEATNUNNEL_HOME/plugins/jdbc/lib/

+## Options
+
+| name | type | required | default | description |
+|------------------------------|--------|----------|-----------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| url | String | Yes | - | The URL of the JDBC connection. Refer to a case: jdbc:mysql://localhost:3306:3306/test |
+| driver | String | Yes | - | The jdbc class name used to connect to the remote data source,<br/> if you use MySQL the value is `com.mysql.cj.jdbc.Driver`. |
+| user | String | No | - | Connection instance user name |
+| password | String | No | - | Connection instance password |
+| query | String | Yes | - | Query statement |
+| connection_check_timeout_sec | Int | No | 30 | The time in seconds to wait for the database operation used to validate the connection to complete |
+| partition_column | String | No | - | The column name for parallelism's partition, only support numeric type. |
+| partition_lower_bound | Long | No | - | The partition_column min value for scan, if not set SeaTunnel will query database get min value. |
+| partition_upper_bound | Long | No | - | The partition_column max value for scan, if not set SeaTunnel will query database get max value. |
+| partition_num | Int | No | job parallelism | The number of partition count, only support positive integer. default value is job parallelism |
+| fetch_size | Int | No | 0 | For queries that return a large number of objects,you can configure<br/> the row fetch size used in the query toimprove performance by<br/> reducing the number database hits required to satisfy the selection criteria.<br/> Zero means use jdbc default value. |
+| common-options | | No | - | Source plugin common parameters, please refer to [Source Common Options](common-options.md) for details |
+
+## 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.
