Change Log

Version 2.0.0-beta1 (2018-09-12)

Tape 2 is a major release that focusses on simplifying the API. Tape 2 also adopts a new file format that allows QueueFile to grow beyond 4GB.

  • New: remove(int) allows atomic removal of multiple elements.
  • Improvement: QueueFile now implements the Closeable and Iterable interface.
  • Improvement: Simplified ObjectQueue API. ObjectQueue now implements the Closeable and Iterable interface. ObjectQueue.Listener has been removed.
  • New: Iterator API allows iterating queue items and stopping iteration early.
  • Improvement: New file format that allows QueueFile to grow beyond 4GB. Tape 2 can continue to operate on the v1 format. You can also force the legacy format by using the forceLegacy option.

Note: Existing queues are currently not migrated to the newer format. This will be added in a future release.
