I have a Play framework application and want to connect to Postgres with Slick and to Apache Phoenix with JDBC simultaneously.
The connection to Postgres works well. But I can not connect to Phoenix from Play.
I tested the connection to Phoenix in a standalone Scala application, without Play, and that worked great.
Here is a code snippet from the standalone application:
import java.sql._
object TestPhoenix extends App {
val connectionString = "jdbc:phoenix:srv1,srv2,srv3,srv4:/hbase"
val request = "select * from MY_TABLE limit 10"
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver")
val conn = DriverManager.getConnection(connectionString)
val stmt = conn.prepareStatement(request)
val rs = stmt.executeQuery()
var hasNext = rs.next()
while (hasNext) {
println(rs.getBytes(1))
hasNext = rs.next()
}
}
I try to use the same code in a controller in the Play application but that doesn't work. And if I try to get a connection with Slick, it doesn't work too:
class DbRequester(connectionString: String, request: String)(implicit val ec: ExecutionContext){
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver")
val db: JdbcBackend.DatabaseDef = Database.forURL(connectionString, driver="org.apache.phoenix.jdbc.PhoenixDriver")
val conn = db.source.createConnection()
val stmt = conn.prepareStatement(request)
def sendRequest() = {
stmt.executeQuery()
}
}
There is a stacktrace:

Also I try to add jdbc dependency to my build.sbt, and that doesn't work too by that reason: https://www.playframework.com/documentation/2.6.x/PlaySlickFAQ#A-binding-to-play.api.db.DBApi-was-already-configured
And there is no way to create a connection with the standard Slick DatabaseConfig, because Slick doesn't have a profile for Apache Phoenix.
So, is there a way to connect to Phoenix, and keep Slick in my project?
