+## 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 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.

If on, you need to<br/>set `xa_data_source_class_name`.
|
+| xa_data_source_class_name | String | No | -
| The xa data source class name of the database Driver, for example, mysql is
`com.mysql.cj.jdbc.MysqlXADataSource`, and<br/>please refer to appendix for
other data sources

| The timeout after the transaction is opened, the default is -1 (never
timeout). Note that setting the timeout may affect<br/>exactly-once semantics
|

+## 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 a simple example of Mysql via Jdbc Sink
+
+```
+# Defining the runtime environment
+env {
+ # You can set flink configuration here
+ execution.parallelism = 1
+ job.mode = "BATCH"
+}
+
+source {
+ # This is a example source plugin **only for test and demonstrate the
feature source plugin**
+ FakeSource {
+ parallelism = 1
+ result_table_name = "fake"
+ row.num = 16
+ schema = {
+ fields {
+ name = "string"
+ age = "int"
+ }
+ }
+ }
+ # If you would like to get more information about how to configure seatunnel

+ # please go to https://seatunnel.apache.org/docs/category/source-v2
+}
+
+transform {
+ # If you would like to get more information about how to configure seatunnel
and see full list of transform plugins,
+ # please go to https://seatunnel.apache.org/docs/category/transform
+}
+
+sink {
+ jdbc {
+ url = "jdbc:mysql://localhost:3306/test"
+ driver = "com.mysql.cj.jdbc.Driver"
+ user = "root"
+ password = "123456"
+ query = "insert into test_table(name,age) values(?,?)"
+ }
+ # If you would like to get more information about how to configure seatunnel
and see full list of sink plugins,
+ # please go to https://seatunnel.apache.org/docs/category/sink-v2
+}
+```
+
+### Exactly-once :
+
+> For accurate write scene we guarantee accurate once
+
+```
+jdbc {
+ url = "jdbc:mysql://localhost:3306/test"
+ driver = "com.mysql.cj.jdbc.Driver"
+
+ max_retries = 0
+ user = "root"
+ password = "123456"
+ query = "insert into test_table(name,age) values(?,?)"
+
+ is_exactly_once = "true"
+
+ xa_data_source_class_name = "com.mysql.cj.jdbc.MysqlXADataSource"
+}
+```
+
+### CDC(Change data capture) event
+
+> CDC change data is also supported by us
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`.**

|
+| 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.

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

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.
