Azure Table Storage

What is Azure Table Storage?

Azure Table Storage is a highly scalable NoSQL datastore that lets you store semi‑structured data without a fixed schema. It offers:

• Low latency read/write operations
• Automatic partitioning and replication
• Pay‑as‑you‑go pricing
• Strong consistency guarantees

Ideal use‑cases include IoT telemetry, user profiles, inventory, and more.

Core Concepts

• Table – a collection of entities.
• Entity – a set of properties with a unique PartitionKey and RowKey.
• PartitionKey – groups entities for scalability.
• RowKey – uniquely identifies an entity within a partition.
• Property – name/value pair; supported types include string, int, bool, DateTime, binary.

Quick .NET Sample

Insert, query, and delete an entity using the Azure.Data.Tables SDK.

using Azure;
using Azure.Data.Tables;

var connectionString = "<your_connection_string>";
var tableClient = new TableClient(connectionString, "People");

// Create table if not exists
await tableClient.CreateIfNotExistsAsync();

// Create an entity
var entity = new TableEntity("partition1", Guid.NewGuid().ToString())
{
    { "FirstName", "Jane" },
    { "LastName", "Doe" },
    { "Email", "jane.doe@example.com" },
    { "Age", 30 }
};

await tableClient.AddEntityAsync(entity);

// Query entity
await foreach (var e in tableClient.QueryAsync(e => e.PartitionKey == "partition1"))
{
    Console.WriteLine($"{e.RowKey}: {e.GetString("FirstName")} {e.GetString("LastName")}");
}

// Delete entity
await tableClient.DeleteEntityAsync(entity.PartitionKey, entity.RowKey);
