Full Changelog: v4.0.0-rc.1...v4.0.0-rc.2

v4.0.0-rc.1

• Added PostgreSQLQueueSchema and PostgreSQLQueueOffsetsAdapter.
  • This schema is similar to the original one, except it allows filtering messages with a custom WHERE clause.
  • It doesn't support customer groups.
  • It allows deleting messages from the table after acking (optional).
• Added NewDelayedPostgreSQLPublisher and NewDelayedPostgresSQLSubscriber
  • They work on top of the conditional schema and use the delay component implemented in ThreeDotsLabs/watermill#469
  • The idea is to receive messages with a delay or at a given time in a simple way.
• Reworked the SchemaAdapter and OffsetsAdapter interfaces (Breaking change -> will bump the major to v4).
  • We had a few instances where some details have been missing from one of the interface methods. It makes it difficult to extend this library with new features, as each will require a major version bump, and we want to avoid it if possible.
  • To mitigate this, we're moving to a params struct passed to the methods instead of raw arguments. It adds some verbosity but allows extending the params if needed with no breaking changes to the library.
  • The methods now also return errors.
  • Migration: if you don't use a custom schema/offsets adapter, you don't need to do anything. If you do, change the methods to implement the new interfaces. Use values from the params argument and return errors.

What's Changed

• fixed support for MariaDB by @roblaszczak in #30

Full Changelog: v3.0.0...v3.0.1

v3.0.0

What's Changed

• Added back exactly-once delivery for Postgres by @roblaszczak in #28
• Added AckDeadline option with default value of 30s for Postgres by @roblaszczak in #28

We bumped major, because:

• We wanted to provide sensible defaults for AckDeadline and add exactly-once-delivery support by default - someone could in theory depend on the original behaviour,
• Postgres now uses sql.LevelRepeatableRead isolation level,
• This is a breaking change because of extended OffsetsAdapter interface.
• We also changed string, []interface to Query type in SchemaAdapter and OffsetsAdapter.

Update guide:

• Ensure that you don't need AckDeadline longer than the default (30s),
• If you have a custom SchemaAdapter or OffsetsAdapter interface implementation, please change string, []interface to Query.
• If you have a custom OffsetsAdapter implementation, please add BeforeSubscribingQueries(topic string, consumerGroup string) []Query method to OffsetsAdapter. For MySQL it can be empty. For PostgreSQL we recommend using implementation from DefaultPostgreSQLOffsetsAdapter.
