Each entity can have up to 252 properties, which are all name-value pairs. The main components of the service are tables, entities, and properties. This article's programming language is not yet supported in the premium offering, but will be added in the future.Īzure Table storage is a NoSQL datastore that you can use to store and query huge sets of structured, non-relational data.

You can copy the code or use my NuGet library.The content in this article applies to Azure Table storage. These two helper methods show how to do this and how to convert the ticks string back to DateTimeOffset. Before using it as a PrimaryKey or RowKey we do need to convert this to a string while making sure all future values have the same length with leading zeroes when necessary. One way to ensure this is by converting the current DateTime to a ever-decreasing number of ticks by subtracting it from the DateTime.Max value.

However, we can use the fact that all rows in the Azure Table Storage are sorted by PartitionKey + RowKey to our advantage. This could be narrowed down by for example knowing on which day a record was added and filtering accordingly, but we’d probably still get multiple rows to check manually for the newest one.
