Problem Summary:
Currently, number of storage read thread is immutable. However, in some cases, such as reading from remote storage with high latency, we need to improve read throughput by improving read concurrency.
Add a parameter
profiles.default.dt_read_thread_count_scaleand the number of storage read thread is equal to multiply number of logical cpu cores bydt_read_thread_count_scale.What is changed and how it works?
