Component Summary of Changes Action Required?
WherobotsDB Migrated from Scala 2.12 to Scala 2.13. Yes, for Scala developers.
WherobotsAI Migrated from Scala 2.12 to Scala 2.13. Yes, for Scala developers.

Migration to Scala 2.13

To ensure future compatibility with Apache Spark 4, we are updating WherobotsDB's Scala version from 2.12 to 2.13.

Who is Affected?

This change impacts any customer who:

  1. Compiles and deploys custom Scala applications or User-Defined Functions (UDFs) as .jar files onto the Wherobots platform.
  2. Uses the Scala kernel to write Scala notebooks on the Wherobots platform.

Required Action

  • To migrate a Wherobots Notebook, edit the notebook's contents so that it works with the Scala 2.13 compiler.

  • All custom Scala code must be migrated to Scala 2.13 to ensure continued usage.

    To migrate your Scala code, you must:

  1. Update your build environment to use a Scala 2.13.x compiler.
  2. Update all dependencies in your project from their _2.12 versions to their _2.13 versions.
  3. Recompile your project to produce a new .jar file compatible with Scala 2.13.
  4. Deploy the new artifact to Wherobots.

For any Scala libraries that you do not own (e.g., open-source projects), you must update those libraries to a version that is compiled against Scala 2.13.

Complete the following steps for each dependency:

  1. Identify Your Project's Dependencies: Review your project's build configuration file (such as build.sbt, pom.xml, or build.gradle) and list all external Scala libraries you are importing.

  2. Find the Scala 2.13 Version of Each Library: For each library, you will need to find its new artifact published for Scala 2.13.

    How can I find my library's 2.13-compatible artifact?

    Go to the library's official website, GitHub page, or a repository like Maven Central and search for the correct artifact ID. It will likely mention _2.13

    Using SPARK_EXTENSION as an example: Migrate from SPARK_EXTENSION_2.12-2.12.0-3.5.jar to SPARK_EXTENSION_2.13-2.13.0-3.5.jar
