If desired, your application can include its own logic to assemble the pages of results into one dataset. It also returns an appropriate `UnprocessedKeys` value so you can get the next page of results. If you request more than 100 items, `BatchGetItem` returns a `ValidationException` with the message “Too many items requested for the BatchGetItem call.”įor example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52 items (so as not to exceed the 16 MB limit). You can use this value to retry the operation starting with the next item to get. If a partial result is returned, the operation returns a value for `UnprocessedKeys`. `BatchGetItem` returns a partial result if the response size limit is exceeded, the table's provisioned throughput is exceeded, or an internal processing failure occurs. You identify requested items by primary key.Ī single operation can retrieve up to 16 MB of data, which can contain as many as 100 items. The `BatchGetItem` operation returns the attributes of one or more items from one or more tables.

Construct and pass an instance of `Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to enable retries and extended timeouts. The `:access_key_id`, `:secret_access_key`, and `:session_token` options.ĮC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. When `:credentials` are not configured directly, the following locations will be searched for credentials: `Aws::CognitoIdentit圜redentials` - Used for loading credentials from the Cognito Identity service. `Aws::ECSCredentials` - Used for loading credentials from instances running in ECS. `Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance. `Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout. `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`. `Aws::AssumeRoleWebIdentit圜redentials` - Used when you need to assume a role after providing credentials via the web. `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
`Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.
`Aws::Credentials` - Used for configuring static, non-refreshing credentials. This can be an instance of any one of the following classes:
