scullxbones / pekko-persistence-mongo Goto Github PK

Would it be possible to support Scala 3? The core Pekko libs support it.

The akka-persistence-mongo persistence plugin had 2 variants to choose from regarding the used MongoDB driver:

• official mongo-scala-driver (now EOL)
  • the linked dependency is EOL, the scala driver is now available at org.mongodb.scala:mongo-scala-driver_2.13:4.8.2
  • the documentation for the Scala driver is now accessible here: http://mongodb.github.io/mongo-java-driver/4.8/driver-scala/
• ReactiveMongo driver
  • last release 1.0.10: "Dec 18, 2021"

In order to have a "future proof" driver also supporting the latest MongoDB versions and in order to reduce maintenance efforts, I suggest to only support a single driver in pekko-persistence-mongo.
As we in Eclipse Ditto had a very good and stable experience with the former mongo-scala-driver variant of akka-persistence-mongo - and this is the "official" driver from MongoDB I would suggest to only support this variant in the future.

As the replacement is org.mongodb.scala:mongo-scala-driver_2.13:4.8.2 with documentation here: http://mongodb.github.io/mongo-java-driver/4.8/driver-scala/, I would suggest to support that driver only.

This driver supports MongoDB version 3.6 (which maybe is important for MongoDB "replacements" like AWS DynamoDB supporting only up to MongoDB 3.6 due to license issues) up to 6.1: https://www.mongodb.com/docs/drivers/java/sync/current/compatibility/

If you have a collection of existing akka persistence data and try to migrate over to pekko using this plugin, you'll get this error:

com.mongodb.MongoCommandException: Command failed with error 85 (IndexOptionsConflict): 'Index with name: pekko_persistence_metadata_pid already exists with a different name'

where in the old version of this library it seems the index was named akka_persistence_metadata_pid and you'll have to wipe your instance of mongo so the index can be recreated with the new name

Hey,

I'm really excited to use this! But it seems like you aren't publishing any snapshots yet. Of course I can do a clone and make the jar, which I have, but it would be cool to just grab the jar that you publish.

Thanks for making this awesome project!

Thanks for your work on this project.

Would it be possible to add GitHub labels to the project? pekko and pekko-persistence would be useful. It's good for apps like https://index.scala-lang.org/ which uses the labels to categorise the Scala libs.
