  2. Useful James, thanks.

    One question we are often asked regarding cool blob storage is the access / retrieval time. i.e. Does it take longer to extract data from Cool Blob Store than the equivalent Hot (I understand there is a penalty charge with cold)?

    Consider a situation where you have a HDInsight Cluster sitting over Hot storage for ah-hoc analysis with swathes of data archived in Cold Storage. What if you want to perform some (rare/adhoc) analysis on a data set that resides in Cold Storage?

    Assuming you have to first move/copy it into Hot storage, perform the analysis and move it back/delete. 1) Is this the correct approach and 2) what’s the retrieval time from Cold to Hot? (Compared with moving from Hot to Hot as I realise it will be size dependent)

    • Hi Steve,

      The retrieval time with cool blob storage is the same as hot storage. The only difference is the SLA (99.9% to 99%). So no need to move the cold storage to hot for performance reasons.
