In February 2017, Microsoft announced the general availability of Blob Auditing for Azure SQL Database. While auditing features were available before in Azure, this is a huge leap forward, especially in having more granular control over what audit records are captured.
Before Blob Auditing, there was Table Auditing. This is something I like to equate to the C2 auditing feature of SQL Server. It’s only configurable options were ON or OFF. In reality, Table Auditing has a few more controls than that, but you get the idea. There was no way to audit actions against one specific table. Blob Auditing provides us with that level of granularity. However, controlling that granularity cannot be accomplished through the Azure Portal; it can only be done with PowerShell or REST API.
