Cassandra - Driver Version 2.5.1 - Upgrade?

sigurd · March 27, 2019, 2:19pm

Hey guys,

I’m working on a akka streams app based on alpakka 1.0 rc1 (cassandra, slick, kafka).
It works very nice, thank you for that!
I’m little bit wondering about the old cassandra driver version 2.5.1 which is used.

github.com

akka/alpakka/blob/master/project/Dependencies.scala

import sbt._
import Keys._

object Dependencies {

  val Scala211 = "2.11.12"
  val Scala212 = "2.12.7"
  val Scala213 = "2.13.0-M5"
  val ScalaVersions = Seq(Scala212, Scala211, Scala213)

  val AkkaVersion = sys.env.get("AKKA_SERIES") match {
    case Some("2.4") => sys.error("Akka 2.4 is not supported anymore")
    case _ => "2.5.21"
  }

  val AwsSdkVersion = "1.11.476"
  val AwsSdk2Version = "2.5.0"
  val AkkaHttpVersion = "10.1.7"

  val CouchbaseVersion = "2.7.2"

Is there any known issue with the newer drivers (2.6, 2.7.1)?

Hi Sigurd,

No, I’m not aware of any problems with newer Cassandra drivers when using Alpakka Cassandra.

We plan to re-work Alpakka Cassandra quite a bit past Alpakka 1.0 where we will bring in parts of the Akka Persistence Cassandra projects session handling.

See https://github.com/akka/alpakka/issues/1213

Cheers,
Enno.

Hi Enno,
thank for your reply. Good news.
I read about the rework but I’m unsure which motivation is there. Its about peformance or safe processing?

The motivation is that the CassandraSession in Akka Persistence Cassandra offers a great API that complements the source/flow/sink APIs in Alpakka. Especially for “one element operations” that are better expressed with Future or CompletionStage.
The other part is that users want to use CassandraSession when not using Akka Persistence Cassandra – see https://github.com/akka/akka-persistence-cassandra/issues/390

Cheers,
Enno.
