⚠️ Version 0.8.0 contains breaking changes to transition to River's new unique jobs implementation and to enable broader, more flexible application of unique jobs. Detailed notes on the implementation are contained in the original River PR, and the notes below include short summaries of the ways this impacts this client specifically.

Users should upgrade backends to River v0.12.0 before upgrading this library in order to ensure a seamless transition of all in-flight jobs. Afterward, the latest River version may be used.

Breaking

  • Breaking change: The return type of Client#insert_many has been changed. Rather than returning just the number of rows inserted, it returns an array of all the InsertResult values for each inserted row. Unique conflicts which are skipped as duplicates are indicated in the same fashion as single inserts (the unique_skipped_as_duplicated attribute), and in such cases the conflicting row will be returned instead. PR #32.
  • Breaking change: Unique jobs no longer allow total customization of their states when using the by_state option. The pending, scheduled, available, and running states are required whenever customizing this list. PR #32.

Added

  • The UniqueOpts class gains an exclude_kind option for cases where uniqueness needs to be guaranteed across multiple job types. PR #32.

  • Unique jobs utilizing by_args can now also opt to have a subset of the job's arguments considered for uniqueness. For example, you could choose to consider only the customer_id field while ignoring the other fields:

    UniqueOpts.new(by_args: ["customer_id"])

    Any fields considered in uniqueness are also sorted alphabetically in order to guarantee a consistent result across implementations, even if the encoded JSON isn't sorted consistently. PR #32.

Changed

  • Unique jobs have been improved to allow bulk insertion of unique jobs via Client#insert_many.

    This updated implementation is significantly faster due to the removal of advisory locks in favor of an index-backed uniqueness system, while allowing some flexibility in which job states are considered. However, not all states may be removed from consideration when using the by_state option; pending, scheduled, available, and running states are required whenever customizing this list. PR #32.

  • Update REXML dependency. PR #28.
