• All BulkWriteBatch es created via BulkWriteBatch.getNextBatch use the same ConnectionDescription as the first batch, despite not necessarily being executed using the same connection. This means, BulkWriteBatch.getBulkWriteException/BulkWriteBatchCombiner.getErrorNonNullable create exceptions with potentially incorrect ServerAddress es.
  • The code behaved this way since the introduction of retryable writes.
• Another driver-by improvement we could do, is to start using SessionContext instead of OperationContext in BulkWriteBatch, as it does not need OperationContext.

Addressing the source code notes tagged with TODO-JAVA-6223 is in scope of this ticket.
