Using Cerulean you can easily change access tier (hot, cool, and archive) of one or more blobs and or virtual folders.
When changing access tier of multiple items (blobs and/or virtual folders), a background task is initiated and that task
takes care of performing the operations on selected blobs and virtual folders. For multiple items, access tier of blobs are
changed using bulk/batch operation which allows you to change access tier of up to 250 blobs in a single operation thus making
it extremely fast.
In case of blobs, Cerulean simply goes through the list of blobs and then changes their access tier. In case of virtual folder,
Cerulean first lists the blobs in the virtual folder and then changes the access tier of blobs fetched.
When rehydrating blobs (i.e. changing the access tier of an archived blob to hot or cool), Cerulean enables you to provide a
reydrate priority (standard or high). When you choose "high" rehydrate priority, blobs are rehydrated faster (usually in a few hours).
Changing blob access tier for multiple blobs in Cerulean is extremely fast. This is because Cerulean uses blob batch operation to perform
this operation which can change acccess tier of up to 250 blobs in a single request (instead of 1 blob in a single request).
