0.1.0 - 2026-07-15

Initial experimental release of DuckDB-backed Oban support through QuackDB.

Added

  • Added Oban.Engines.QuackDB with job insertion, claiming, scheduling, lifecycle, bulk operation, pruning, rescue, and update support.
  • Added Oban.Migrations.QuackDB with DuckDB-native job storage, a fetch index, and serialized uniqueness locking.
  • Added exact and keyed uniqueness checks for job arguments and metadata.
  • Added bounded retries for classified QuackDB transaction conflicts, with support for disabling retries inside nested transaction contexts.
  • Added single-node support for Oban's Cron, Pruner, and Lifeline plugins.
  • Added explicit validation for unsupported prefixes, peers, notifiers, and Reindexer configuration.

Compatibility

  • Requires Elixir 1.19+, Oban 2.23.x, QuackDB 0.5.17+, and DuckDB 1.5.3+.
  • Supports single-node operation with an isolated peer and local process-group notifications.
  • Does not support prefixes, distributed peers, or the PostgreSQL-specific Reindexer plugin.
  • Oban 2.23.0 doesn't support testing: :manual with an external migrator outside an Ecto migration runner; normal runtime operation and direct package migrations are supported.
