[elasticsearch怎么和数据库同步]elasticsearch和mysql的数据同步采用哪种方案合适。

时间:2021-07-01 10:21:17 帮助过:60人阅读

  最近公司在使用elasticsearch,使用的是6.5版本的。其中有一个需求就是需要把数据库已有的数据同步到elasticsearch中来,调研了几种方案。

  logstash,elasticsearch-jdbc,自己实现。

  暂时采用的是elasticsearch-jdbc,但是,同步的过程中,出现错误。错误在最下面

  我想请问哪种方案合适?如果是elasticsearch-jdbc合适,那么,下面问题如何解决?
