How to clear the data buffer cache for an Azure SQL database I want to do some performance testing on an Azure SQL database.

For SQL Server, I've read that DBCC DROPCLEANBUFFERS can be used 
to clear the data buffer cache, and DBCC FREEPROCCACHE can be used to clear the execution plan cache.

But neither are supported for Azure SQL databases. For the execution plan cache, ALTER DATABASE SCOPED CONFIGURATION CLEAR PROCEDURE_CACHE
seems to be an alternative. But I can't find an alternative for the data buffer cache.

How do I clear the data buffer cache for an Azure SQL database?
Azure SQL Database does not have at this time something like DBCC DROPCLEANBUFFERS available for cleaning the data on buffer pool, but scaling up or down the tier of the database has the same effect of DBCC DROPCLEANBUFFERS  and reduces the memory allocation also for the first few minutes.

Hope this helps.
