It can be easily integrated into apps and websites using its easy-to-use SDKs. ), Exists is false but you also provide a Value. Use FilterExpression instead. If neither Select nor AttributesToGet are specified, DynamoDB defaults to ALL_ATTRIBUTES when accessing a table, and ALL_PROJECTED_ATTRIBUTES when accessing an index. Adds or removes replicas in the specified global table. Each element consists of an attribute name and a value for that attribute. Represents a target tracking scaling policy configuration. Items that do not satisfy the FilterExpression criteria are not returned. Setting this, the size of the global cache storing One or more values that can be substituted in an expression. You try to perform multiple operations on the same item in the same BatchWriteItem request. You could then use these values in an expression, such as this: For more information on expression attribute values, see Condition Expressions in the Amazon DynamoDB Developer Guide. Creates a new table from an existing backup. Calling the describeContinuousBackups operation. Valid values for ExportFormat are DYNAMODB_JSON or ION. You can restore your table to any point in time during the last 35 days. The tags to be assigned to the Amazon DynamoDB resource. The following comparison operators are available: EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN. Use FilterExpression instead. The number of values in the list depends on the ComparisonOperator being used. The AWS KMS customer master key (CMK) that should be used for the AWS KMS encryption. For more information, see Filter Expressions in the Amazon DynamoDB Developer Guide. The name of the global table to describe. Currently supported options are: A set of options to pass to the low-level For an overview on tagging DynamoDB resources, see Tagging for DynamoDB in the Amazon DynamoDB Developer Guide. For example: An attribute of type Binary Set. No set data types are allowed. For example, with a simple primary key, you only need to provide a value for the partition key. Calling the listContributorInsights operation. If set to SIZE, the response includes statistics about item collections (if any), that were modified during the operation and are returned in the response. One or more values to evaluate against the supplied attribute. Only applies The Amazon Resource Name (ARN) associated with the table to export. The Amazon Resource Name (ARN) of the backup the table was archived to, when applicable in the archival reason. Removes the association of tags from an Amazon DynamoDB resource. Parallel processing reduces latency, but each specified put and delete request consumes the same number of write capacity units whether it is processed in parallel or not. You cannot define a filter expression based on a partition key or a sort key. The resource states are: An Endpoint object representing the endpoint URL for service requests. This topic provides general information about the PutItem API. To have DynamoDB return fewer items, you can provide a FilterExpression operation. DynamoDB updates this value approximately every six hours. An attribute of type String Set. Replica-specific read capacity units. Use KeyConditionExpression instead. 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. Set this value to get remaining results, if NextToken was returned in the statement response. The total size of the specified table, in bytes. If a requested item does not exist, it is not returned in the result. ), You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. For more information, see Provisioned Throughput in the Amazon DynamoDB Developer Guide. the signature version to sign If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Waits for a given DynamoDB resource. If set, you can use that this value in the subsequent request to get the remaining results. The name of an existing global secondary index, along with new provisioned throughput settings to be applied to that index. You no longer need to update schema or map the table properties to class members. With the Document API, you no longer need to use the DynamoDB Object Mapper; instead, you access individual fields within data objects directly. If there are no unprocessed items remaining, the response contains an empty UnprocessedItems map. Calling the updateContinuousBackups operation. The target value for the metric. A FilterExpression cannot contain partition key or sort key attributes. We recommend using PAY_PER_REQUEST for unpredictable workloads. The condition can optionally perform one of several comparison tests on a single sort key value. Describes the current status for contributor insights for the given table and index, if applicable. To retrieve them, call ListTagsOfResource again, with NextToken set to this value. The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. For more information, see QueryFilter in the Amazon DynamoDB Developer Guide. subsequent event callback registration. Code definitions. ALL_PROJECTED_ATTRIBUTES - Allowed only when querying an index. 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. Contains the details of the global table. the maximum amount of retries to AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). Document objects are used as the unit of transfer between your mobile app and Amazon DynamoDB. For more information, see Working with Tables in the Amazon DynamoDB Developer Guide. Use this value to start a new operation, excluding this value in the new request. Starts table data replication to the specified Kinesis data stream at a timestamp chosen during the enable workflow. A string that identifies one or more attributes to retrieve from the specified table or index. If any attributes are present in the item that are part of an index key schema for the table, their types must match the index key schema. The Query operation finds items based on primary key values. The AWS SDK for JavaScript also supports higher level abstractions for simplified development. If you query or scan a local secondary index and request only attributes that are projected into that index, the operation will read only the index and not the table. To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. request sent by this service object. These are in addition to the primary key attributes and index key attributes, which are automatically projected. For example, with a simple primary key, you only need to provide a value for the partition key. Contains a description of the table export. If there is no matching item, GetItem does not return any data and there will be no Item element in the response. Defaults to 0 milliseconds. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide. License. This is because not all data types that can be stored in DynamoDB can be represented in JSON. The output from ListTables is paginated, with each page returning a maximum of 100 table names. A map of table name to a list of items. The AWS KMS customer master key (CMK) of the replica that will be used for AWS KMS encryption. error. See the respective resource Represents the provisioned throughput settings for a specified table or index. Each DynamoDB table can only have up to one tag with the same key. Represents the auto scaling properties of the table. If any attributes are present in the item that are part of an index key schema for the table, their types must match the index key schema. The AWS KMS customer master key (CMK) of the replica that should be used for AWS KMS encryption. Each API operation is exposed as a The name of the manifest file for the export task. An attribute of type Binary. The DynamoDB Document API does not currently support: The Document API is currently in beta and we would like to hear about the use cases you would like us to support. The new provisioned throughput settings for the specified table or index. A successful UpdateContinuousBackups call returns the current ContinuousBackupsDescription. Calling the batchExecuteStatement operation. API operation. The error message associated with the PartiQL batch resposne. ConditionCheck  —   Applies a condition to an item that is not being modified by the transaction. This attribute will automatically be cleared when DynamoDB detects that the table's AWS KMS key is accessible again. The following action values are available for UpdateExpression. After continuous backups and point in time recovery are enabled, you can restore to any point in time within EarliestRestorableDateTime and LatestRestorableDateTime. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. Although a strongly consistent read might take more time than an eventually consistent read, it always returns the last updated value. Calling the restoreTableToPointInTime operation. The Amazon Resource Name (ARN) that uniquely identifies the index. PROVISIONED - Sets the read/write capacity mode to PROVISIONED. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is empty. Describes Region-specific settings for a global table.
