> This ticket is to create a JDBC Driver (thin client) for the new SQL
> interface (SOLR-7560). As part of this ticket a driver will be added to the
> Solrj libary under the package: *org.apache.solr.client.solrj.io.sql*
> Initial implementation will include basic *Driver*, *Connection*, *Statement*
> and *ResultSet* implementations.
> Future releases can build on this implementation to support a wide range of
> JDBC clients and tools.
> *Syntax using parallel Map/Reduce for aggregations*:
> {code}
> Properties props = new Properties();
> props.put("aggregationMode", "map_reduce");
> props.put("numWorkers", "10");
> Class.forName("org.apache.solr.client.solrj.io.sql.DriverImpl").newInstance();
> Connection con =
> DriverManager.getConnection("jdbc:solr://<zkhost:port>?collection=<collection>",
> props);
> Statement stmt = con.createStatement();
> ResultSet rs = stmt.executeQuery("select a, sum(b) from tablex group by a
> having sum(b) > 100");
> while(rs.next()) {
> String a = rs.getString("a");
> double sumB = rs.getDouble("sum(b)");
> }
> {code}
> *Syntax using JSON facet API for aggregations*:
> {code}
> Properties props = new Properties();
> props.put("aggregationMode", "facet");
> Class.forName("org.apache.solr.client.solrj.io.sql.DriverImpl").newInstance();
> Connection con =
> DriverManager.getConnection("jdbc:solr://<zkhost:port>?collection=<collection>",
> props);
> Statement stmt = con.createStatement();
> ResultSet rs = stmt.executeQuery("select a, sum(b) from tablex group by a
> having sum(b) > 100");
> while(rs.next()) {
> String a = rs.getString("a");
> double sumB = rs.getDouble("sum(b)");
> }
> {code}
