+## Description
+
+Write data through jdbc. Support Batch mode and Streaming mode, support
concurrent writing, support exactly-once
+semantics (using XA transaction guarantee).

+| 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 | No | -
| Use this sql write upstream input datas to database. e.g `INSERT
...`,`query` have the higher priority
|
+| database | String | No | -
| Use this `database` and `table-name` auto-generate sql and receive upstream
input datas write to database.<br/>This option is mutually exclusive with
`query` and has a higher priority.
|
+| table | String | No | -
| Use database and this table-name auto-generate sql and receive upstream
input datas write to database.<br/>This option is mutually exclusive with
`query` and has a higher priority.
|
+| primary_keys | Array | No | -
| This option is used to support operations such as `insert`, `delete`, and
`update` when automatically generate sql.
|
+| support_upsert_by_query_primary_key_exist | Boolean | No | false
| Choose to use INSERT sql, UPDATE sql to process update events(INSERT,
UPDATE_AFTER) based on query primary key exists. This configuration is only
used when database unsupport upsert syntax. **Note**: that this method has low
performance |
+| connection_check_timeout_sec | Int | No | 30
| The time in seconds to wait for the database operation used to validate the
connection to complete.
|
+| max_retries | Int | No | 0
| The number of retries to submit failed (executeBatch)
|
+| batch_size | Int | No | 1000
| For batch writing, when the number of buffered records reaches the number
of `batch_size` or the time reaches `batch_interval_ms`<br/>, the data will be
flushed into the database
|
+| batch_interval_ms | Int | No | 1000
| For batch writing, when the number of buffers reaches the number of
`batch_size` or the time reaches `batch_interval_ms`, the data will be flushed
into the database
|
+| is_exactly_once | Boolean | No | false
| Whether to enable exactly-once semantics, which will use Xa transactions.
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
|
+| max_commit_attempts | Int | No | 3
| The number of retries for transaction commit failures
|
+| transaction_timeout_sec | Int | No | -1
| The timeout after the transaction is opened, the default is -1 (never
timeout). Note that setting the timeout may affect<br/>exactly-once semantics
|
+| auto_commit | Boolean | No | true
| Automatic transaction commit is enabled by default
|
+| common-options | | no | -
| Sink plugin common parameters, please refer to [Sink 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 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.
+
+```
+# 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"
+ }
+ }
