+
+## Description
+
+> Use `Xa transactions` to ensure `exactly-once`. So only support
`exactly-once` for the database which is

+
+| Name | Type | Required | Default |
Description
|
+|------------------------------|------------|----------|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| url | String | Yes | - | The
URL of the JDBC connection. Refer to a case:
jdbc:kingbase8://localhost:54321/test
|
+| driver | String | Yes | - | The
jdbc class name used to connect to the remote data source, should be
`com.kingbase8.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 column and
string type column.
|
+| partition_lower_bound | BigDecimal | No | - | The
partition_column min value for scan, if not set SeaTunnel will query database
get min value.
|
+| partition_upper_bound | BigDecimal | 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 to improve 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 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 DB2. 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"
Review Comment:
such as: @NickYoungPeng
```
source {
FakeSource {
row.num = 10
map.size = 10
array.size = 10
bytes.length = 10
string.length = 10
schema = {
fields {
c_map = "map<string, array<int>>"
c_array = "array<int>"
c_string = string
c_boolean = boolean
c_tinyint = tinyint
c_smallint = smallint
c_int = int
c_bigint = bigint
c_float = float
c_double = double
c_decimal = "decimal(16, 1)"
c_null = "null"
c_bytes = bytes
c_date = date
c_timestamp = timestamp
}
}
}
}
