When creating a HDInsights Hadoop cluster in Azure there are two storage options. Either Azure Data Lake Store (ADLS) or Azure Blob Storage.
What are the real differences between these two options and how do they affect the performance?
I found this page https://docs.microsoft.com/en-us/azure/data-lake-store/data-lake-store-comparison-with-blob-storage But it is not very specific, only uses very general terms like "ADLS is optimized for analytics".
Does it mean that its better for storing the HDInsights file system? And if ADLS is indeed faster then why not use it for non-analytics data as well?
