Changelog

Disclaimer: This is a major release in the sense that the changes in this release affects a larger part of the codebase. In particular, polling logic and per-database customizations (like LIMIT). There is good test-coverage for all of these changes, but I would still advice to let it sit in a test-environment for a while before promoting to production, to verify it is working as expected and does not produce any noise in the logs. Se PR #371 for more details.

🚀 Features

• PR #371 (31c4bab). Recommended to see PR description and code for more details. Closes #264 #273 #337 #348
  • Adds explicit LIMIT to polling for most databases (SqlServer, Mysql, MariaDB, Oracle). This might improve query-plans.
  • Lays groundwork to support lock-and-fetch for more dialects than PostgreSQL
  • JdbcRunner transaction and batch-update support (micro-jdbc)

📝 Documentation

• bbe25d7 Add Swan to the list of users (#426)
• a47057d Update README with new Lightyear link (#421)
• e098bd2 Improve Examples (#420)
• ff6c39f Add links to third-party extensions, in particular
  • bekk/db-scheduler-ui is admin-ui for the scheduler. It shows scheduled executions and supplies simple admin-operations such as "rerun failed execution now" and "delete execution".
  • rocketbase-io/db-scheduler-log is an extention providing a history of executions, including failures and exceptions.

🎉 Contributors & Sponsorship

We'd like to thank the following people for their contributions:

Additionally, a big thanks to our two new sponsors, matt-snider and robinheghan 🎉.

• Changing to semantic versioning.
• It is now possible to sponsor work on db-scheduler and so contributing to sustainable open-source development. Many thanks to rocketbase-io and gauthamchandra, our first sponsors 🎉
• PR #368 changes shutdown sequence to avoid executions that are slow to stop will be detected as dead since the heartbeat-thread already has stopped. Fixes #365.
• PR 357 adds support for specifying JdbcCustomizer in spring boot via DbSchedulerCustomizer. The same PR also fixes missing serialVersionUID for Serializable classes. This will be a breaking change for everyone already using dynamic recurring tasks, i.e PersistentCronSchedule and friends. See notes below.

Breaking changes Unfortunately a couple of Serializable classes missing serialVersionUID was added in previous releases (releated to dynamic recurring tasks). This was a mistake, as that will break Java serialization for all changes to the classes, even if they are backwards compatible. This is addressed in this release, but means that anyone already serializing these classes will get a InvalidClassException after upgrading to this version or later. The workaround is to migrate away from these classes before upgrading, and then optionally migrating back to fixed classes after upgrade (or not). See section on migrating serializers in README and SerializerWithFallbackDeserializers for hints on how to migrate serialization. This only affects Java serialization.
