IAM auth work in progress. Last tickets for index builds in code review. We'll pin to a specific commit that contains all the features we need for now, and bump the driver version whenever go 1.4.0 is released. 2020-05-01: Updated target date to 2020-05-15 (+2wks) Encountered major issues with the js tests and had to do rewrites of the tests, pushing out the target date. The test updates were a blocker for testing other tasks within the epic, development work is otherwise moving along as expected. 2020-04-20: On track for target of 2020-05-01 Started work on new mongodump format and index changes in mongorestore AWS auth support is ready for work 2020-04-02: Setting initial target date to 2020-05-01 (4 Weeks) Design in progress, nearing completion AWS and collection name length sections are complete Putting finishing touches on the index build section A single scope and design are shared between the Tools and Mirror 4.4 support epics Prioritized ahead of Mirror 4.4 support Varsha and Evgeni will join the project when execution starts (currently working on non-epic work)
