Balancer random migrations stop working when there are views/timeseries
Last update date:
4/15/2024
Affected products:
MongoDB Server
Affected releases:
8.0.0-alpha2
Fixed releases:
No fixed releases provided.
Description:
Info
This is a test only issue, since the balancer never attempt to move unsharded collection in production, only for testing. In suites with "random_migrations: true" the balancer will try to fetch all the unsharded collection in the cluster and will try to get their UUID, the problem is that it does this also for views that does not have an UUID. So in the presence of views/timeseries all balancer round will fail.
