用的多版本分离配置 elasticsearch7.9.1: name: elasticsearch desc: elasticsearch version: 7.9.1 driver: org.elasticsearch.plugin.nlpcn.SqlPlug keyword_prefix: ` keyword_suffix: ` alias_prefix: \' alias_suffix: \'

make sure org.elasticsearch.plugin.nlpcn.SqlPlug is the right jdbc driver

[zhanghucheng]

which jdbc driver should be use

[zhanghucheng]

I try " com.facebook.presto.jdbc.PrestoDriver " and "org.elasticsearch.xpack.sql.jdbc.EsDriver" but not work

[gavin-fu]

make sure org.elasticsearch.plugin.nlpcn.SqlPlug is the right jdbc driver

你好，目前 davinci中的可视化组件基本都使用到了子查询，但现在绝大部分 ES JDBC驱动对于子查询的支持并不完善，这是不是意味着 ES作为 davinci数据源并不合适？

[zhanghucheng]

es是可选择性 并不是唯一性 所以用它做为数据源也多了一条路挺好的

[leping]

使用es作为数据源，es版本7.12， davinci版本03.0 1、每次查询会计算count，davinci报错。 2、davici对es的某些查询报错。 在davinci新版本会修复对es的支持吗
