Users could easily create connector instances with configurations via REST API. 5 | 6 | There are two types of connectors: source connector and sink connector. A source connector is used for pulling data from a data source (e.g. RDBMS). 7 | The data is sent to corresponding message queue and expected to be consumed by one or many sink connectors. 8 | A sink connector receives message from the queue and loads into a data destination (e.g. data warehouse). 9 | Developers should implement source or sink connector interface to run their specific job. 10 | 11 | Usually, connectors rely on a concrete message queue for data transportation. The message queue decouples source connectors from sink connectors. 12 | In the meantime, it provides capabilities such as failover, rate control and one to many data transportation etc. 13 | Some message queues (e.g. Kafka) provide bundled connect frameworks and a various of connectors developed officially or by the community. 14 | However, these frameworks are lack of interoperability, which means a connector developed for Kafka cannot run with 15 | RabbitMQ without modification and vice versa. 16 | 17 | ![dataflow](flow.png "dataflow") 18 | 19 | A connector follows OpenMessaging Connect could run with any message queues which support OpenMessaging API. 20 | OpenMessaging Connect provides a standalone runtime which uses OpenMessaging API for sending and consuming message, 21 | as well as the key/value operations for offset management. 22 | 23 | ## Connector 24 | 25 | This runtime is based on interface [openmessaging-connector](https://github.com/openmessaging/openmessaging-connector). 26 | 27 | ## Runtime quick start 28 | 29 | ### Prerequisite 30 | 31 | * 64bit JDK 1.8+; 32 | * Maven 3.2.x; 33 | * A running MQ cluster; 34 | 35 | ### Build 36 | 37 | ``` 38 | mvn clean install -Dmaven.test.skip=true 39 | ``` 40 | 41 | ### Run Command Line 42 | 43 | ``` 44 | ## Enter runtime directory 45 | cd runtime/ 46 | 47 | ## run run_worker.sh 48 | sh ./run_worker.sh 49 | ``` 50 | 51 | ### Log Path 52 | 53 | Default path is: 54 | ``` 55 | ${user.home}/logs/omsconnect/ 56 | ``` 57 | 58 | If you see "The worker XXX boot success." without any exception, it means worker started successfully. 59 | 60 | ### Make Sure Worker Started Successfully 61 | 62 | Use http request to get all alive workers in cluster: 63 | ``` 64 | GET /getClusterInfo 65 | ``` 66 | You will see all alive workers' id with latest heartbeat timestamp. 67 | 68 | ### Run The Example Mysql Source Connector 69 | 70 | Use the following http request, to start a mysql source connector as an example. 71 | ``` 72 | GET http://(your worker ip):(port)/connectors/(Your connector name)?config={"connector-class":"io.openmessaging.mysql.connector.MysqlConnector","oms-driver-url":"oms:rocketmq://localhost:9876/default:default","mysqlAddr":"localhost","mysqlPort":"3306","mysqlUsername":"username","mysqlPassword":"password","source-record-converter":"io.openmessaging.connect.runtime.converter.JsonConverter"} 73 | ``` 74 | Note to replace the arguments in "()" with your own mysql setting. 75 | 76 | #### Config introduction 77 | 78 | |key |nullable|default |description| 79 | |------------------|--------|-----------|-----------| 80 | |connector-class |false | |Full class name of the impl of connector| 81 | |oms-driver-url |false | |An OMS driver url, the data will send to the specified MQ| 82 | |mysqlAddr |false | |MySQL address| 83 | |mysqlPort |false | |MySQL port| 84 | |mysqlUsername |false | |Username of MySQL account| 85 | |mysqlPassword |false | |Password of MySQL account| 86 | |source-record-converter |false | |Full class name of the impl of the converter used to convert SourceDataEntry to byte[]| 87 | |whiteDataBase |false | |DataBase Name which you want to source data 88 | |whiteTable |true | |Table Name which you want to source data (choosable) 89 | 90 | ### Verify Mysql Source Connector Started Successfully 91 | 92 | Make a mysql row update, your will found the MQ you config receive a message, and the message's topic name is the table name. 93 | 94 | ## Note 95 | 96 | Module odar-mysql-connector is just a simple example of source connector. 97 | This module is base on [RocketMQ Mysql](https://github.com/apache/rocketmq-externals/tree/master/rocketmq-mysql) with a little code modified in order to implement connector interface. 98 | User can reference this module to implement other source or sink connector. 99 | 100 | ## RoadMap 101 | 102 | 1. Implement WorkerSinkTask wrapper in runtime; 103 | 2. Import openMessaging impl and connector impl dynamically in runtime, rather than import them in pom file; 104 | 3. An overall optimization of runtime module, provide a better interaction. 105 | 4. Implementation of various source and sink connector. -------------------------------------------------------------------------------- /flow.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/openmessaging/openmessaging-connect-odar/dec822705b1130f17b869bd39e641372f88fdbee/flow.png -------------------------------------------------------------------------------- /odar-mysql-connector/pom.xml: -------------------------------------------------------------------------------- 1 | 17 | 20 | 21 | io.openmessaging 22 | openmessaging-odar 23 | 0.0.1-SNAPSHOT 24 | 25 | 4.0.0 26 | 27 | odar-mysql-connector 28 | 29 | 30 | io.openmessaging 31 | openmessaging-api 32 | 0.3.1-alpha 33 | 34 | 35 | com.github.shyiko 36 | mysql-binlog-connector-java 37 | 0.12.1 38 | 39 | 40 | mysql 41 | mysql-connector-java 42 | 8.0.11 43 | 44 | 45 | org.slf4j 46 | slf4j-api 47 | 1.7.5 48 | 49 | 50 | ch.qos.logback 51 | logback-classic 52 | 1.0.13 53 | 54 | 55 | com.alibaba 56 | druid 57 | 1.0.31 58 | 59 | 60 | commons-codec 61 | commons-codec 62 | 1.9 63 | 64 | 65 | junit 66 | junit 67 | 4.11 68 | test 69 | 70 | 71 | com.alibaba 72 | fastjson 73 | 74 | 75 | io.openmessaging 76 | openmessaging-connector 77 | 0.1.0-beta 78 | 79 | 80 | 81 | 82 | -------------------------------------------------------------------------------- /odar-mysql-connector/src/main/java/io/openmessaging/mysql/Config.java: -------------------------------------------------------------------------------- 1 | /* 2 | * Licensed to the Apache Software Foundation (ASF) under one or more 3 | * contributor license agreements.
