Description

Currently, all AddData methods return a Task, however, this task is not for an individual add/remove operation, but for the current batch.

This is confusing: users often try to await the returned task, which is natural; but the task will never complete, because the batch is not yet full, and user code is stuck waiting.

• Deprecate AddData, RemoveData methods
• Add new void Add and void Remove methods
• Add new BatchTask property to get the task for the current batch
