If you want to create multiple tables with secondary indexes on them, you must create the tables sequentially. This index can be any local secondary index or global secondary index. AWS SDK for Java Documentation. If the specified table does not exist, DynamoDB returns a ResourceNotFoundException. For more information, see QueryFilter in the Amazon DynamoDB Developer Guide. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is empty. The Region where the new replica will be created. (This attribute does not appear for indexes that were created during a CreateTable operation. In the second part of this blog, we will describe how to integrate the Document API into a real Android app and provide a sample app that shows the Document API in action. A map of one or more table names and, for each table, a map that describes one or more items to retrieve from that table. The AWS SDK for Java provides a Java API for AWS infrastructure services. When provided in this manner, the API fetches the next page of results. For example, {"S":"6"} does not equal {"N":"6"}. Defaults to true. An ordered array of up to 25 TransactGetItem objects, each of which contains a Get structure. If you provide Segment, you must also provide TotalSegments. The name of the TTL attribute used to store the expiration time for items in the table. Contains a description of the table export. Amazon DynamoDB is AWS managed key-value and document database that delivers single-digit millisecond performance at any scale. Checks the status of continuous backups and point in time recovery on the specified table. The endpoint URI to send requests For example: SET myNum = myNum + :val. ConsistentRead - The consistency of a read operation. used in all services (unless overridden by apiVersions). A map of attribute names to AttributeValue objects, representing the item as it appeared before the DeleteItem operation. specify the accessKeyId and secretAccessKey options directly. If an item can be added to the index, DynamoDB will do so. Represents the settings for a global table in a Region that will be modified. To list backups for a given table, specify TableName. We recommend using PAY_PER_REQUEST for unpredictable workloads. You can call DescribeBackup at a maximum rate of 10 times per second. ADD - DynamoDB creates an item with the supplied primary key and number (or set of numbers) for the attribute value. The Region where the replica needs to be created. DynamoDB rejects the entire TransactGetItems request if any of the following is true: A conflicting operation is in the process of updating an item to be read. The table must have DynamoDB Streams enabled, with the stream containing both the new and the old images of the item. The endpoint should be a string like 'https://{service}. Currently supported options are: a String in YYYY-MM-DD format The DynamoDB table that will be restored. When provided in this manner, this API fetches the next page of results. 'us-east-1' regional endpoints. List backups associated with an AWS account. A map of attribute name to attribute values, representing the primary key of the item to be written by PutItem. Remove a global secondary index from the table. You can call DescribeContinuousBackups at a maximum rate of 10 times per second. Body signing You can create or delete only one global secondary index per UpdateTable operation. Calling the describeContributorInsights operation. The complete key schema for a local secondary index, which consists of one or more pairs of attribute names and key types: Represents the GSI properties for the table when the backup was created. begins_with ( sortKeyName, :sortkeyval ) - true if the sort key value begins with a particular operand. Items that do not satisfy the FilterExpression criteria are not returned. A Query operation always returns a result set. For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide. Time at which the automatic on-demand backup created by DynamoDB will expire. DELETING - The global table is being deleted. You can convert between JSON and Document objects. Role ARN used for configuring the auto scaling policy. You are using DynamoDB like DocumentClient.If you switch your line var ddb = new AWS.DynamoDB({apiVersion: '2012-08-10'}); to var docClient = new AWS.DynamoDB.DocumentClient();, your queries will work.. With plain DynamoDB class instance you should also specify data types of your keys manually, you can find the reference to data types here.However, with DocumentClient class … Information about item collections, if any, that were affected by the DeleteItem operation. For example: "BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="], "M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}, "L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, application auto scaling scales out your scalable target immediately. If any requested operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs, the failed operations are returned in the UnprocessedItems response parameter. The table export will be a snapshot of the table's state at this point in time. Valid values for ExportFormat are DYNAMODB_JSON or ION. DynamoDB kann aus .NET-Anwendungen mithilfe des AWS SDK für .NET aufgerufen werden. This topic provides general information about the PutItem API. You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. Use this to compensate for clock skew The global secondary index name, if applicable. This enables you to select the API that you feel is better for your situation. Calling the updateTableReplicaAutoScaling operation. Restores the specified table to the specified point in time within EarliestRestorableDateTime and LatestRestorableDateTime. To create a placeholder for repeating occurrences of an attribute name in an expression. A single Query operation will read up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using FilterExpression. For type Number, value comparisons are numeric. ALL - All of the table attributes are projected into the index. They are defined by the following objects: Put  —   Initiates a PutItem operation to write a new item. Subsequent TransactWriteItems calls with the same client token return the number of read capacity units consumed in reading the item. Size of the table in bytes. The ID of the AWS account that owns the bucket the export will be stored in. The scaling policy to apply for scaling target global table or global secondary index capacity units. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total. This value is an Amazon Resource Name (ARN). If you query or scan a local secondary index and request only attributes that are projected into that index, the operation reads only the index and not the table. UPDATING - The global table is being updated. As items are deleted, they are removed from any local secondary index and global secondary index immediately in the same eventually consistent way as a standard delete operation. The primary key of the item to be deleted. 'latest' to use the latest possible version. Represents one or more local secondary indexes on the table. service are listed in "Waiter Resource States" below. A map of tables and their respective keys that were not processed with the current response. For an overview on tagging DynamoDB resources, see Tagging for DynamoDB in the Amazon DynamoDB Developer Guide. To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. These attributes can include scalars, sets, or elements of a JSON document. A map of attribute names to AttributeValue objects, representing the primary key of the item to delete. Empty String and Binary attribute values are allowed. (This attribute does not appear for indexes that were created during a CreateTable operation.). whether to apply a clock skew Use the : (colon) character in an expression to dereference an attribute value. If none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchGetItem returns a ProvisionedThroughputExceededException. Providing a ClientRequestToken makes the call to TransactWriteItems idempotent, meaning that multiple identical calls have the same effect as one single call. Use this value as the ExclusiveStartTableName in a new request to obtain the next page of results, until all the table names are returned. A single call to BatchWriteItem can write up to 16 MB of data, which can comprise as many as 25 put or delete requests. If you use a programming language that supports concurrency, you can use threads to write items in parallel. Each of the CRUD operations within the Document API either accepts or returns a Document object. The maximum read capacity units that your account allows you to provision for a new table that you are creating in this Region, including the read capacity units provisioned for its global secondary indexes (GSIs). For information on how to call the PutItem API using the AWS SDK in specific languages, see the following: PutItem in the AWS Command Line Interface. The value of TotalSegments corresponds to the number of application workers that will perform the parallel scan. The GetItem operation returns a set of attributes for the item with the given primary key. If the existing data type is a set, and if the Value is also a set, then the Value is added to the existing set. For a composite primary key, you must provide values for both the partition key and the sort key. If set, you can use that this value in the subsequent request to get the remaining results. A DynamoDB item associated with a BatchStatementResponse.
