This PR removes the use of multiprocessing in favor of multithreading. There were instances where using multiprocessing was problematic in containers (e.g., getting an accurate cpu count as well as memory issues). In all cases we were more interested in concurrency than parallelism (using multithreading for I/O for managing keys on s3) .
This is a relatively major change internally for many of the s3 related functions, but it should not affect common users. Users can still set the env variable
DISDAT_CPU_COUNT
and the system will create thread pools with exactly that number of threads. Otherwise it will use the system cpu count and set threads = 2* that amount.In addition, this removes
six.moves.urllib
dependencies and removes a number of print statements in lieu of logger.info() calls (useful for those using the API instead of the CLI).
