UpdateTableRequest Class

Container for the parameters to the UpdateTable operation.

Updates the provisioned throughput for the given table. Setting the throughput for a table helps you manage performance and is part of the provisioned throughput feature of Amazon DynamoDB.

The provisioned throughput values can be upgraded or downgraded based on the maximums and minimums listed in the Limits section in the Amazon DynamoDB Developer Guide.

The table must be in the ACTIVE state for this operation to succeed. UpdateTable is an asynchronous operation; while executing the operation, the table is in the UPDATING state. While the table is in the UPDATING state, the table still has the provisioned throughput from before the call. The new provisioned throughput setting is in effect only when the table returns to the ACTIVE state after the UpdateTable operation.

You cannot add, modify or delete local secondary indexes using UpdateTable . Local secondary indexes can only be defined at table creation time.

Syntax

public class UpdateTableRequest : AmazonWebServiceRequest
         IRequestEvents

Examples

This example shows how to update the throughput settings of a table. New throughput will be 40 ReadCapacityUnits and 50 WriteCapacityUnits.

UpdateTable sample

// Create a client
AmazonDynamoDBClient client = new AmazonDynamoDBClient();

// Define new table throughput:
//  Table will now have capacity of 40 reads and 50 writes
ProvisionedThroughput throughput = new ProvisionedThroughput
{
    ReadCapacityUnits = 40,
    WriteCapacityUnits = 50
};

// Compose the UpdateTable request
UpdateTableRequest request = new UpdateTableRequest
{
    TableName = "SampleTable",
    ProvisionedThroughput = throughput
};

// View new table properties
TableDescription tableDescription = client.UpdateTable(request).UpdateTableResult.TableDescription;
Console.WriteLine("Table name: {0}", tableDescription.TableName);
Console.WriteLine("Throughput: Reads = {0}, Writes = {1}",
    tableDescription.ProvisionedThroughput.ReadCapacityUnits,
    tableDescription.ProvisionedThroughput.WriteCapacityUnits);
