We currently violate ODF spec that specifies unsigned types for offset and op columns.

This was done due to very old parquet version in Spark 3.2, but recent upgrade to Spark 3.5 allows us to finally rectify this.

This task is to:

  • Verify logical types support in Flink
  • Write a test in kamu-cli that checks all major engine permutations for compatibility
  • Create a transition plan for moving all engines to unsigned types
  • Perform the upgrade
