One solution brought about a my sources incredibly hot partition with the chance of lousy functionality crafting log messages; the other solution resulted in very poor question functionality due to the requirement to scan each individual partition inside the table to retrieve log messages for a specific time span. Blob storage provides a Resources much better Answer for such a situation which is how Azure Storage Analytics outlets the log facts it content collects. This section outlines how Storage Analytics shops log facts in blob storage being an illustration of this approach to storing knowledge that you typically query by selection. Storage Analytics outlets log messages in the delimited format in several blobs. The delimited format causes it to be simple to get a consumer application to parse the data from the log information. Storage Analytics makes use of a naming convention for blobs that lets you Find the blob (or blobs) that incorporate the log messages for which you might be searching.
