Hi, I happened to be playing with the this. Sharing some information I have so far.
For the architecture view of the avatica server implementation, found this diagram => https://raw.githubusercontent.com/julianhyde/share/master/slides/avatica-architecture.png 1) The JSON is how the remote communicate talk to server. The implementation is in org.apache.calcite.avatica.remote.RemoteService.java. 2) I haven't try with this url jdbc:avatica:remote:factory=... 3) The ConnectionFactory is where the jdbc connection is being created on the server side. On not able to access CalciteConnectionImpl, you can resolve that by having your implementation of ConnectionFactory in org.apache.calcite.jdbc package. Below are my working project in scala based on csv example A) CsvConnectionFactory.scala --------------------------------------------------------------------------------------------- package org.apache.calcite.jdbc import org.apache.calcite.avatica.Meta.Factory import java.sql.DriverManager class CsvConnectionFactory extends Factory { def create(x$1: java.util.List[String]): org.apache.calcite.avatica.Meta = { val connection = DriverManager.getConnection( "jdbc:calcite:model=/model.json", "admin", "admin"); return new CalciteMetaImpl(connection.asInstanceOf[CalciteConnectionImpl]) } } --------------------------------------------------------------------------------------------- B) To start csv example as Server run org.apache.calcite.avatica.server.Main with argument "org.apache.calcite.jdbc.CsvConnectionFactory" C) JDBC Client Code for connecting --------------------------------------------------------------------------------------------- package org.apache.calcite.jdbc import java.sql.Connection import java.sql.DriverManager object HelloWorld { def main(args: Array[String]) { val port = 8765 val connection: Connection = DriverManager.getConnection("jdbc:avatica:remote:url=http://localhost:"; + port) val rs = connection.createStatement().executeQuery("select * from EMPS") while (rs.next){ println(rs.getString("NAME")) } } } --------------------------------------------------------------------------------------------- Hope this help.
