SDK already support concurrent read, CSDK also need to support it for
improving read performance.
I already raise a PR for it:https://github.com/apache/carbondata/pull/2946 I want to support readAllParallel in SDK, but I don't know how to save
the data for different threads. Anyone has good idea for it?
What's more, for the concurrent read in C++, I already provide the
interface for user. I tried with thread and
join/detach for concurrent, are there any better solution for it?
