Research direction
Start with the org.apache.beam.sdk.io.DynamicAvroDestinations JavaDoc and review its documentation for the DestinationT type. Update it to state that user-defined destination objects must implement hashCode and equals, then verify the JavaDoc clearly explains the requirement and its relationship to dynamic destinations.
