2026-04-16: Kernel Open Source Community Sync Notes

[OussamaSaoudi]

Major New Proposals or Features

Updates from kernel

• making kernel write relative paths refactor!: store relative paths in Delta log by default #2359
• Crate split is moving forward
  • Cyclic crate dependencies for Engine <-> kernel are the main challenge
• There's an issue with enabling certain properties on create table. Create table will be disabled for certain properties

• Open discussion

• Is there an option to write absolute paths?
  • shallow clones write absolute paths
• Nanosecond timestamp proposal is up. 64bit nanoseconds poses some issues since it doesn't cover a full gamut of dates
• Need to figure out how timezones are handled
  • Timezone normalizes time to a UTC, while NTZ doesn't carry that information.
  • May need a dependency on NTZ. This is fine since Delta already has a notion of dependencies.
• It is useful for the read path to return relative path. Only exception is shallow clones.
  • Need to ensure engine writers write the correct kind of path
