CHANGELOG.md

Release History

5.20.0-beta.1 (Unreleased)

Features Added

Breaking Changes

• Do not remove x-opt-partition-key message annotation when publishing events. If event is received from an Event Hub, it may contain x-opt-partition-key message annotation. If this event is published to another Event Hub, previous version of the Event Hubs SDK did not pass this annotation to the next Event Hub. Starting with this version:

  • if the event is sent with SendOptions or CreateBatchOptions containing null partition key, the existing x-opt-partition-key message annotation will be used when publishing the event. This is a new behavior.
  • if the event is sent with SendOptions or CreateBatchOptions containing non-null partition key, this partition key will be used. This behavior did not change.

  If you relied on the previous behavior, make sure to clear the x-opt-partition-key message annotation before re-sending the event. (#43039)

Bugs Fixed

• Set partition key in addition to partition id when publishing events with EventHubsBufferedProducerClient. (#43039)
• Do not remove x-opt-sequence-number, x-opt-offset, x-opt-enqueued-time, x-opt-publisher message annotations when re-sending events received from another Event Hub. Message annotations should not be modified by the SDK and Event Hubs will overwrite these values when the event is published. (#43039)

• Creating an EventDataBatch is not exposed.
• Getting ReceiverRuntimeInformation from EventHubConsumer is not implemented.
• EventHubClient does not clean up its EventHubPublishers and EventHubConsumers. These need to be closed manually by calling EventHubPublisher.close() or EventHubConsumer.close().
• Creating more than two concurrent EventHubClients or EventHubConsumers does not work. Limit usage of concurrent clients and consumers to two to avoid failures.
