Azure Table Storage

• A NoSQL key-value store for large semi-structured datasets.
• Supports flexible data schema.
• Performs OData-based queries

Features

• Allows you to store and query huge sets of structured, non-relational data. And as demand grows, your tables will scale-out.

• Scale-up without having to manually shard your dataset.
• The data is replicated three times within a region using geo-redundant storage.
• An entity has a limit of 1MB in size.
• Store data sets that do not require complex joins, foreign keys, or stored procedures, and can be denormalized for fast access.
• Table storage is used to store flexible data sets such as user data for web applications, device information, or other types of metadata the service requires.
• You can store any number of entities in a table, up to the storage account’s capacity limit.
