 Description   

Create a new blacklisted feature flag that will follow the following behavior matrix:

featureFlag/behaviour Version protocol Create Collection Balancer CheckMetadataConsistency
featureFlagTrackUnshardedCollectionsOnShardingCatalog Do not throw with UNSHARDED requests regardless of feature flag value Allow creation of unsplittable collections if enabled Prevent balancing of unsplittable collections if enabled
  • Normal check
  • Check unsplittable collection chunk
  • All collections are registered
  • Single chunk on primary shard
featureFlagUnsplittableCollectionsOnNonPrimaryShards Throw in shard if UNSHARDED is found for splittable collections if enabled Allow creation of unsplittable collections in non primary shards if enabled Same as above
  • Normal checks
  • Check unsplittable collection chunk
  • All collections are registered
  • Do not check only chunk on primary shard for unsplittable collection
