Hi @Mivik, thank you very much for using OpenDAL in your project. I’m the maintainer of OpenDAL and I’m currently considering this discussion.

In short, I’m planning to remove all blocking implementations under the hood (Currently, only the fs and the in-memory struct support this.) and make BlockingOperator solely a wrapper for Operator.

Since bijou is one of the users of BlockingOperator, I’m opening this issue to ask: What would happen if OpenDAL changes its BlockingOperator implementation? Would this change break your code a lot?
