Wildfly群集Clickhouse数据源

Question

I'm using clustered clickhouse database. I want to define a wildfly datasource to connect clustered clickhouse. How should I define Connection URL in wildfly datasource?

Answer 1

Need to use one of the existing JDBC drivers and define connection URL like this:

<datasources ..>
  <datasource ..>
    <!-- .. -->
    <connection-url>jdbc:clickhouse://<host>:<port>[/<database>]</connection-url>
    <!-- .. -->
  </datasource ..>
</datasources>

Answer 2

I found chproxy , This allows me to load balancing clickhouse cluster. You can configure it to which nodes are in the cluster and use it with one connection url.
