     In the Cinder repository, I noticed that the BlockDeviceDriver driver is being deprecated, and was eventually be removed with the Queens release.


In my use case, the instances using Cinder perform intense I/O, thus iSCSI or LVM is not a viable option - benchmarked them several times, since Juno, unsatisfactory results.For data processing scenarios is always better to use local storage than any SAN/NAS solution.

So I felt a great need to know why we deprecated it.If there has any better one to replace it? What do you suggest to use once BlockDeviceDriver is removed?Can you tell me about this?Thank you very much!

Best Regards
