Managing blobs

Blobs are little pieces of data you can store in EVA. We use blobs for images, synchronization files, configuration documents and much more. To manage blobs, we have a specific set of services:

  • StoreBlob
  • ListBlobs
  • GetBlobInfo
  • CreateBlob
  • DeleteBlob

A blob consists of two important bits of information; a plain text Base64 encoded file and a MIME type defining what type of file that is.

To easily store a blob, we use StoreBlob:
