# Elasticsearch Pipeline Connector | ||
|
||
Elasticsearch Pipeline 连接器可以用作 Pipeline 的 Data Sink, 将数据写入 Elasticsearch。 本文档介绍如何设置 Elasticsearch Pipeline 连接器。 | ||
|
||
|
||
How to create Pipeline | ||
---------------- | ||
|
||
从 MySQL 读取数据同步到 Elasticsearch 的 Pipeline 可以定义如下: | ||
|
||
```yaml | ||
source: | ||
type: mysql | ||
name: MySQL Source | ||
hostname: 127.0.0.1 | ||
port: 3306 | ||
username: admin | ||
password: pass | ||
tables: adb.\.*, bdb.user_table_[0-9]+, [app|web].order_\.* | ||
server-id: 5401-5404 | ||
|
||
sink: | ||
type: elasticsearch | ||
name: Elasticsearch Sink | ||
hosts: http://127.0.0.1:9092;http://127.0.0.1:9093 | ||
|
||
route: | ||
- source-table: adb.\.* | ||
sink-table: default_index | ||
description: sync adb.\.* table to default_index | ||
|
||
pipeline: | ||
name: MySQL to Elasticsearch Pipeline | ||
parallelism: 2 | ||
``` | ||

Usage Notes | ||
-------- | ||
* The written index of Elasticsearch will be `namespace.schemaName.tableName` string of TableId,this can be changed using route function of pipeline. | ||
|
||
* The feature for automatic Elasticsearch index creation is not yet supported. | ||
|
||
Data Type Mapping | ||
---------------- | ||
Elasticsearch stores document in a JSON string. So the data type mapping is between Flink CDC data type and JSON data type. | ||
