You can make [Druid SQL](../querying/sql.md) queries using the [Avatica JDBC driver](https://calcite.apache.org/avatica/downloads/).
We recommend using Avatica JDBC driver version 1.22.0 or later.
We recommend using Avatica JDBC driver version 1.22.0 or later. Note that starting with Avatica 1.21.0, you may need to set the [`transparent_reconnection`](https://calcite.apache.org/avatica/docs/client_reference.html#transparent_reconnection) property to `true` if you notice intermittent query failures.

Since we are using 1.23 now should this be 1.23 ? Or since the change came after 1.21 this should be 1.21 ? I think 1.23 but have no pressing case against it as well

I don't know where that original recommendation for the version came from, so your suggestion for versions would probably be what we go with.
