It's a local emulator, what kind of high demmand in this region ?
回答1:
According to the official documentation.
By default, you can create up to 25 single partition collections, or 1 partitioned collection using the Azure Cosmos DB Emulator. By modifying the PartitionCount value, you can create up to 250 single partition collections or 10 partitioned collections, or any combination of the two that does not exceed 250 single partitions (where one partitioned collection = 25 single partition collection).
So basically, if you want to create more partitioned collections or more single-partition collections, just increase the PartitionCount when starting from the command-line:
CosmosDB.Emulator.exe /PartitionCount=100
回答2:
The CosmosDB emulator has some limitations and this is the generic message that it will throw if you exceed those limitations.
The reason you got that is because you tried to make more than 10 collections in a database, but there are other reasons you might get the same error as well.
You can read more about the differences between the Emulator and the service here.

Someone else on my team could get this working without the need for CosmosDB.Emulator.exe /PartitionCount=100. We could see that the containers where not being created.
Microsoft explains how to resolve this issue: https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator#set-partitioncount
- Reset Data
- Exit CosmosDb
- Go to
%LOCALAPPDATA%\CosmosDBEmulatorand delete all content - Restart your machine for good measure
You should now be able to retry and all should work.
