CreateGlobalTableCommand

Creates a global table from an existing table. A global table creates a replication relationship between two or more DynamoDB tables with the same table name in the provided Regions.

This documentation is for version 2017.11.29 (Legacy) of global tables, which should be avoided for new global tables. Customers should use Global Tables version 2019.11.21 (Current)  when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017.11.29 (Legacy).

To determine which version you're using, see Determining the global table version you are using . To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see Upgrading global tables .

If you want to add a new replica table to a global table, each of the following conditions must be true:

  • The table must have the same primary key as all of the other replicas.

  • The table must have the same name as all of the other replicas.

  • The table must have DynamoDB Streams enabled, with the stream containing both the new and the old images of the item.

  • None of the replica tables in the global table can contain any data.

If global secondary indexes are specified, then the following conditions must also be met:

  • The global secondary indexes must have the same name.

  • The global secondary indexes must have the same hash key and sort key (if present).

If local secondary indexes are specified, then the following conditions must also be met:

  • The local secondary indexes must have the same name.

  • The local secondary indexes must have the same hash key and sort key (if present).

Write capacity settings should be set consistently across your replica tables and secondary indexes. DynamoDB strongly recommends enabling auto scaling to manage the write capacity settings for all of your global tables replicas and indexes.

If you prefer to manage write capacity settings manually, you should provision equal replicated write capacity units to your replica tables. You should also provision equal replicated write capacity units to matching secondary indexes across your global table.

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { DynamoDBClient, CreateGlobalTableCommand } from "@aws-sdk/client-dynamodb"; // ES Modules import
// const { DynamoDBClient, CreateGlobalTableCommand } = require("@aws-sdk/client-dynamodb"); // CommonJS import
const client = new DynamoDBClient(config);
const input = { // CreateGlobalTableInput
  GlobalTableName: "STRING_VALUE", // required
  ReplicationGroup: [ // ReplicaList // required
    { // Replica
      RegionName: "STRING_VALUE",
    },
  ],
};
const command = new CreateGlobalTableCommand(input);
const response = await client.send(command);

CreateGlobalTableCommand Output

Type
Description
$metadata
Required
ResponseMetadata
Metadata pertaining to this request.
GlobalTableDescription

Contains the details of the global table.

Throws

Name
Fault
Details
GlobalTableAlreadyExistsException
client

The specified global table already exists.

InternalServerError
server

An error occurred on the server side.

InvalidEndpointException
client
LimitExceededException
client

There is no limit to the number of daily on-demand backups that can be taken.

For most purposes, up to 500 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, RestoreTableFromBackup, and RestoreTableToPointInTime.

When you are creating a table with one or more secondary indexes, you can have up to 250 such requests running at a time. However, if the table or index specifications are complex, then DynamoDB might temporarily reduce the number of concurrent operations.

When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account.

There is a soft account quota of 2,500 tables.

GetRecords was called with a value of more than 1000 for the limit request parameter.

More than 2 processes are reading from the same streams shard at the same time. Exceeding this limit may result in request throttling.

TableNotFoundException
client

A source table with the name TableName does not currently exist within the subscriber's account or the subscriber is operating in the wrong Amazon Web Services Region.

DynamoDBServiceException
Base exception class for all service exceptions from DynamoDB service.
