Currently mognoexport and mogodump use a single find query per collection. We could use the mongosync partitioning logic to run multiple queries in parallel per collection.
Acceptance criteria:
- Test the performance impact of running multiple queries in parallel to copy data.
- If the test shows good results, add parallel queries to mongoexport and mongodump. Also:
-
- Consider adding an option to change the number of parallel queries per collection
- This is particularly important for mongoimport since if the --sort option is set, then we cannot use parallel queries.
