| # RocketMQ | ||
|
|
||
| > RocketMQ sink connector | ||
| > | ||
| ## Description | ||
|
|
||
| Write Rows to a Apache RocketMQ topic. | ||
|
|
||
| ## Key features | ||
|
|
||
| - [x] [exactly-once](../../concept/connector-v2-features.md) | ||
|
|
||
| By default, we will use 2pc to guarantee the message is sent to RocketMQ exactly once. | ||
|
|
||
| ## Options | ||
|
|
||
| | name | type | required | default value | | ||
| |----------------------|---------|----------|--------------------------| | ||
| | topic | string | yes | - | | ||
| | name.srv.addr | string | yes | - | | ||
| | acl.enabled | Boolean | no | false | | ||
| | access.key | String | no | | | ||
| | secret.key | String | no | | | ||
| | producer.group | String | no | SeaTunnel-producer-Group | | ||
| | semantic | string | no | NON | | ||
| | partition.key.fields | array | no | - | | ||
| | format | String | no | json | | ||
| | field.delimiter | String | no | , | | ||
| | common-options | config | no | - | | ||
|
|
||
| ### topic [string] | ||
|
|
||
| `RocketMQ topic` name. | ||
|
|
||
| ### name.srv.addr [string] | ||
|
|
||
| `RocketMQ` name server cluster address. | ||
|
|
||
| ### semantic [string] | ||
|
|
||
| Semantics that can be chosen EXACTLY_ONCE/AT_LEAST_ONCE/NON, default NON. | ||
|
|
||
| ### partition.key.fields [array] | ||
|
|
||
| Configure which fields are used as the key of the RocketMQ message. | ||
|
|
||
| For example, if you want to use value of fields from upstream data as key, you can assign field names to this property. | ||
|
|
||
| Upstream data is the following: | ||
|
|
||
| | name | age | data | | ||
| |------|-----|---------------| | ||
| | Jack | 16 | data-example1 | | ||
| | Mary | 23 | data-example2 | | ||
|
|
||
| If name is set as the key, then the hash value of the name column will determine which partition the message is sent to. | ||
|
|
||
| ### format | ||
|
|
||
| Data format. The default format is json. Optional text format. The default field separator is ",". | ||
| If you customize the delimiter, add the "field_delimiter" option. | ||
|
|
||
| ### field_delimiter | ||
|
|
||
| Customize the field delimiter for data format. | ||
|
|
||
| ### common options [config] | ||
|
|
||
| Sink plugin common parameters, please refer to [Sink Common Options](common-options.md) for details. | ||
|
|
||
| ## Examples | ||
|
|
||
| ```hocon | ||
| sink { | ||
| Rocketmq { | ||
| name.srv.addr = "localhost:9876" | ||
| topic = "test-topic-003" | ||
| partition.key.fields = ["name"] | ||
| } | ||
| } | ||
| ``` | ||

| consumer.group = "consumer-group" | ||
| parallelism = 2 | ||
| batch.size = 20 | ||
| schema = { | ||
| fields { | ||
| age = int | ||
| name = string | ||
| } | ||
| } | ||
