| Description |
SummaryAstrolabe creates Atlas clusters in the "cloud-qa" environment to test driver behavior during Atlas planned maintenance tasks. The Atlas "cloud-qa" environment limits the max number of simultaneous clusters we can create (max of 25; TODO: Figure out the real number?), and will either return an API error or take a very long time to create clusters (> 1 hour) if that number is exceeded. To prevent hitting that limit, we need to limit how many Astrolabe Evergreen tasks that create Atlas clusters can run in parallel. Previously, we used the Evergreen distro "ubuntu1804-drivers-atlas-testing" that was specifically configured to only allow a max of 25 (TODO: Figure out the real number). However, there are two problems with that approach:
Instead, we can use
MotivationWho is the affected end user?Who are the stakeholders? How does this affect the end user?Are they blocked? Are they annoyed? Are they confused? How likely is it that this problem or use case will occur?Main path? Edge case? If the problem does occur, what are the consequences and how severe are they?Minor annoyance at a log message? Performance concern? Outage/unavailability? Failover can't complete? Is this issue urgent?Does this ticket have a required timeline? What is it? Is this ticket required by a downstream team?Needed by e.g. Atlas, Shell, Compass? Is this ticket only for tests?Does this ticket have any functional impact, or is it just test improvements?
