Will Azure Block Blob storage store uploaded files are chuck of files? RRS feed

  • Question

  • Hi Friends

    Lets say If I upload a file log.txt of size 200MB as Block Blob. I believe azure will split the file into two blocks let say Block1 and Block2 and upload that to storage container.

    After uploading into storage Block.Will the Block1 and Block2 merged together and saved as log.txt or it will be saved as two blocks?

  • Data lake store is actually the one that is officially recommended to be used for Analytics similar to HDFS, although the concept is similar for blobs, here's a doc that breaks down the Data lake and blob storage https://docs.microsoft.com/en-us/azure/data-lake-store/data-lake-store-comparison-with-blob-storage

  • bSurendiran, you are correct that Block blobs of size 200MB will be split in Azure, however it won't be into two pieces but rather into sets of blocks that are less or equal to 4 MB: This 2min explanation of block blob video explains it well: https://youtu.be/pmrFNH7SIPE?t=2m31s 
    It will be saved as blocks, but the blob name would be the one that would retrieve them. I hope this answers your question.
