Issue - Cosmos DB Limitations || Shared throughputs
Cosmos DB's shared throughput cannot be stretched beyond 25 collections. Quoting Azure documentation ->
Azure Cosmos DB accounts using shared database throughput are now limited to 25 collections per database. This will allow for better throughput sharing across collections. Create additional databases with shared throughput and add more collections or add collections to the same database with dedicated throughput.
In OSDU we are currently at 25 collections. So, we have already hit the limitation.
This would require us to re-organize our collections to multiple databases so that they can scale in a better way.
