LGTM with a small formatting suggestion: if you wanted to use monospace, use backticks (`) instead of single quotes (')

[osharaf-mdb]

If this is meant to be monospace, use backticks (`). Same applied throughout these changes.

Suggested change

	* AZURE provider with EVENTHUB, CONFLUENT, or AZURE_BLOB_STORAGE vendor. For AZURE_BLOB_STORAGE, this should follow the format '{storageAccount}.blob.core.windows.net'.

[christineschen]

I tried this and it seems to get errors because the doc generator converts backticks to single quotes so it comes across as an inconsistency
