es拉取mysql的增量更新代码_MySQL

~~~~~~

目的：实现增量更新

原理

1）第一次全量更新，更新完毕后，删除这个任务。

2）发布增量更新任务即可。

~~~~~~~~~

增量更新任务的模板如下：

 curl -XPUT 'ip:9200/_river/my_jdbc_river/_meta' -d '{"type":"jdbc","jdbc":{"url":"jdbc:mysql://IP:3306/fastooth","user":"dewmobile","password":"dewmobile","sql":"select * from users where updated_at between UNIX_TIMESTAMP(now())*1000-60000 800000 and UNIX_TIMESTAMP(now())*1000 or created_at between UNIX_TIMESTAMP(now())*1000-60000 800000 and UNIX_TIMESTAMP(now())*1000","schedule":"0 0-59 0-23 * * ?","index":"ccc","type":"ddd"}}'
