前言

DataX 是一款由阿里巴巴开源的数据同步工具，它提供了丰富的数据源插件，支持包括但不限于 MySQL、Oracle、HDFS 等多种数据源的同步。以下是几种常见同步场景的 JSON 模板示例。

1. HDFS 到 MySQL (hdfsToMysql)

当您需要将数据从 HDFS 同步到 MySQL 时，可以使用如下的 JSON 模板：

{"job": {"content": [{"reader": {"name": "hdfsreader","parameter": {"path": "/user/hive/warehouse/ads.db/ads_zhy_site_stat_di/date=${dt1}","defaultFS": "hdfs://dn22:8020","fileType": "parquet","skipHeader": false,"column": [{"index":"0","type":"string"},{"index":"1","type":"string"},{"index":"2","type":"int"},{"index":"3","type":"int"},{ "name": "date", "type": "string","value":"${dt1}"}]}},"writer": {"name": "mysqlwriter","parameter": {"writeMode": "insert","username": "cnooc_fuse","password": "root","column": ["`site_id`","`fuel_type`","`vehicle_num`","`through_vehicle_num`","`date`"],"connection": [{"table": ["t_site_flow_stat_day"],"jdbcUrl": "jdbc:mysql://172.0.0.1:8086/cnooc_fuse?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&tinyInt1isBit=false&dontTrackOpenResources=true"}]}}}]
,"setting": {"speed": {"channel": "2"}}}
}

2. HDFS 到 Oracle (hdfsToOracle)

将数据从 HDFS 同步到 Oracle 的 JSON 模板如下：

{"job": {"content": [{"reader": {"name": "hdfsreader","parameter": {"path": "/user/hive/warehouse/mid.db/hky_veh_run_time/dt=${dt}","defaultFS": "hdfs://nn01:8020","fileType": "parquet","skipHeader": false,"column": [{"index":"0","type":"long"},{"index":"1","type":"int"},{"index":"2","type":"int"},{ "name": "dt", "type": "long","value":"${dt}"}]}},"writer": {"name": "oraclewriter","parameter": {"username": "root","password": "root","column": ["TRANS","AD_CODE","RUN_TIME","DT"],"connection": [{"table": ["HKY_VEH_RUN_TIME"],"jdbcUrl": "jdbc:oracle:thin:@172.0.0.1:1521:rdt1"}]}}}],"setting": {"speed": {"channel": "2"}}}
}

3. MySQL 到 HDFS (mysqlToHdfs)

从 MySQL 同步数据到 HDFS 的 JSON 模板示例：

{"job": {"content": [{"reader": {"name": "mysqlreader","parameter": {"username": "cnooc_fuse","password": "root","connection": [{"querySql": ["SELECT id,site_name,area_type,province,city,site_type,company_name,tel,lon,lat,is_cnooc,address, section_code,road_type,road_name,site_state,
recommend_type, manage_type, remark, note, create_user,create_time, update_user, update_time, is_deletedFROM t_site_new "],"jdbcUrl": ["jdbc:mysql://172.0.0.1:8086/cnooc_fuse?allowLoadLocalInfile=false&autoDeserialize=false&allowLocalInfile=false&allowUrlInLocalInfile=false"]}]}},"writer": {"name": "hdfswriter","parameter": {"column": [{"name": "id","type": "int"},{"name": "site_name","type": "string"},{"name": "area_type","type": "int"},{"name": "province","type": "int"},{"name": "city","type": "int"},{"name": "site_type","type": "int"},{"name": "company_name","type": "string"},{"name": "tel","type": "string"},{"name": "lon","type": "double"},{"name": "lat","type": "double"},{"name": "is_cnooc","type": "int"},{"name": "address","type": "string"},{"name": "section_code","type": "string"},{"name": "road_type","type": "string"},{"name": "road_name","type": "string"},{"name": "site_state","type": "string"},{"name": "recommend_type","type": "string"},{"name": "manage_type","type": "string"},{"name": "remark","type": "string"},{"name": "note","type": "string"},{"name": "create_user","type": "string"},{"name": "update_user","type": "string"},{"name": "create_time","type": "string"},{"name": "update_time","type": "string"},{"name": "is_deleted","type": "int"}],"compress": "snappy","defaultFS": "hdfs://nn01:8020","fieldDelimiter":",","fileName": "datax","fileType": "parquet","path": "/user/hive/warehouse/ods.db/ods_tran_logistics_site/","writeMode": "truncate"}}}],"setting": {"speed": {"channel": "2"}}}
}

4. Oracle 到 Doris (oracleToDoris)

将数据从 Oracle 同步到 Doris 的 JSON 模板：

{"job": {"setting": {"speed": {"channel": 1},"errorLimit": {"record": 0,"percentage": 0}},"content": [{"reader": {"name": "oraclereader","parameter": {"column": [
"SERIAL_ID",
"CYCLE",
"REGION_CODE",
"TYPE",
"SRC_REGION",
"DST_REGION",
"SRC_TIME",
"HB_TIME",
"STATUS",
"CREATE_TIME"],"connection": [{"jdbcUrl": ["jdbc:oracle:thin:@//172.0.0.1:32021/s_tsshprod"],"table": ["HEART_BEAT_INFO"]}],"password": "root","splitPk": "","username": "tssh","where": "1=1 and CREATE_TIME >= TO_DATE('${dt}', 'YYYY-MM-DD HH24:MI:SS') - INTERVAL '1:10' HOUR TO MINUTE"}},"writer": {"name": "doriswriter","parameter": {"loadUrl": ["172.0.0.1:8030"],"loadProps": {"format": "json","strip_outer_array": true},"column": [
"serial_id",
"cycle",
"region_code",
"type",
"src_region",
"dst_region",
"src_time",
"hb_time",
"status",
"create_time"],"username": "yunwei","password": "root","postSql": [],"preSql": [],"flushInterval": 30000,"connection": [{"jdbcUrl": "jdbc:mysql://172.0.0.1:9030/collect","selectedDatabase": "collect","table": ["dl_01_heart_beat_info"]}]}}}]}
}
