Hi, I’ve been reading through the history of this ticket and the old PR to understand why it was closed.

From what I can tell, the main issues earlier were:

  • Dependency on expdp / impdp
  • Oracle-specific logic in the base backend
  • Added complexity around cloning data

Question / Idea

I was wondering if a simpler approach could work for Oracle:

  • For parallel tests, create empty cloned test users (with suffixes like _1, _2)
  • Skip exporting/importing data entirely
  • Let Django handle schema creation via migrations and test data via its existing serialization logic

This seems closer to how Django already handles parallel tests and avoids external tools.

Questions

I’m still learning Django internals, so I wanted to ask:

  • Is empty schema cloning considered sufficient for Oracle?
  • Would this be an acceptable direction to revisit this ticket, or is there something I’m missing?

Happy to learn and adjust based on feedback. Thanks!

Replying to Jacob Walls:

Tests are failing.

Thanks for the review. I see the Oracle CI failures in the shared test creation and test runner tests and I’m working on addressing them.
