As the unsharded collections can be of any size need to add tests that that migrating chunks of 100Mb, 1Gb, 10Gb does not break the balancer. Will be part of the suite added in SERVER-37660

Added a document outlining the necessary steps to be taken to get this test to work.

janna.golden I agree - need to separate smoke tests and performance tests where we can scale the instance sizes.

Comment by Janna Golden [ 01/Nov/18 ]

misha.tyulenev sure it needs more resources so needs to be run on a different instance. Do we want to make two different suites (one for SERVER-37660 and one for this ticket) to be run on a bigger instance?

janna.golden it must be a different suite because it needs to run on a different instance

Comment by Janna Golden [ 01/Nov/18 ]

misha.tyulenev do we want to put this in a different suite than the one in SERVER-37660 (maybe even just the normal sharding suite)? I think we should test this separately from testing the functionality/performance of the sharding catalog and wouldn't want this test to start up with 1,000,000 collections in the sharding catalog.
