Crate rusoto_dynamodb

Amazon DynamoDB

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.

With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance degradation, and use the AWS Management Console to monitor resource utilization and performance metrics.

DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an AWS region, providing built-in high availability and data durability.

If you're using the service, you're probably looking for DynamoDbClient and DynamoDb.

Examples

List Tables

The following code shows a simple example of using Rusoto's DynamoDB API to list the names of all tables in a database.

extern crate rusoto_core;
extern crate rusoto_dynamodb;
 
use rusoto_core::Region;
use rusoto_dynamodb::{DynamoDb, DynamoDbClient, ListTablesInput};
 
fn main() {
    let client = DynamoDbClient::new(Region::UsEast1);
    let list_tables_input: ListTablesInput = Default::default();
 
    match client.list_tables(list_tables_input).sync() {
        Ok(output) => {
            match output.table_names {
                Some(table_name_list) => {
                    println!("Tables in database:");
 
                    for table_name in table_name_list {
                        println!("{}", table_name);
                    }
                },
                None => println!("No tables in database!"),
            }
        },
        Err(error) => {
            println!("Error: {:?}", error);
        },
    }
}

Structs

AttributeDefinition	Represents an attribute for describing the key schema for the table and indexes.
AttributeValue	Represents the data for an attribute. Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself. For more information, see Data Types in the Amazon DynamoDB Developer Guide.
AttributeValueUpdate	For the UpdateItem operation, represents the attributes to be modified, the action to perform on each, and the new value for each. You cannot use UpdateItem to update any primary key attributes. Instead, you will need to delete the item, and then use PutItem to create a new item with new attributes. Attribute values cannot be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests with empty values will be rejected with a ValidationException exception.
AutoScalingPolicyDescription	Represents the properties of the scaling policy.
AutoScalingPolicyUpdate	Represents the autoscaling policy to be modified.
AutoScalingSettingsDescription	Represents the autoscaling settings for a global table or global secondary index.
AutoScalingSettingsUpdate	Represents the autoscaling settings to be modified for a global table or global secondary index.
AutoScalingTargetTrackingScalingPolicyConfigurationDescription	Represents the properties of a target tracking scaling policy.
AutoScalingTargetTrackingScalingPolicyConfigurationUpdate	Represents the settings of a target tracking scaling policy that will be modified.
BackupDescription	Contains the description of the backup created for the table.
BackupDetails	Contains the details of the backup created for the table.
BackupSummary	Contains details for the backup.
BatchGetItemInput	Represents the input of a BatchGetItem operation.
BatchGetItemOutput	Represents the output of a BatchGetItem operation.
BatchWriteItemInput	Represents the input of a BatchWriteItem operation.
BatchWriteItemOutput	Represents the output of a BatchWriteItem operation.
BillingModeSummary	Contains the details for the read/write capacity mode.
CancellationReason	An ordered list of errors for each item in the request which caused the transaction to get cancelled. The values of the list are ordered according to the ordering of the TransactWriteItems request parameter. If no error occurred for the associated item an error with a Null code and Null message will be present.
Capacity	Represents the amount of provisioned throughput capacity consumed on a table or an index.
Condition	Represents the selection criteria for a Query or Scan operation: For a Query operation, Condition is used for specifying the KeyConditions to use when querying a table or an index. For KeyConditions, only the following comparison operators are supported: EQ | LE | LT | GE | GT | BEGINS_WITH | BETWEEN Condition is also used in a QueryFilter, which evaluates the query results and returns only the desired values. For a Scan operation, Condition is used in a ScanFilter, which evaluates the scan results and returns only the desired values.
ConditionCheck	Represents a request to perform a check that an item exists or to check the condition of specific attributes of the item..
ConsumedCapacity	The capacity units consumed by an operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the request asked for it. For more information, see Provisioned Throughput in the Amazon DynamoDB Developer Guide.

DynamoDbClient	A client for the DynamoDB API.
Endpoint	An endpoint information details.
ExpectedAttributeValue	Represents a condition to be compared with an attribute value. This condition can be used with DeleteItem, PutItem or UpdateItem operations; if the comparison evaluates to true, the operation succeeds; if not, the operation fails. You can use ExpectedAttributeValue in one of two different ways: Use AttributeValueList to specify one or more values to compare against an attribute. Use ComparisonOperator to specify how you want to perform the comparison. If the comparison evaluates to true, then the conditional operation succeeds. Use Value to specify a value that DynamoDB will compare against an attribute. If the values match, then ExpectedAttributeValue evaluates to true and the conditional operation succeeds. Optionally, you can also set Exists to false, indicating that you do not expect to find the attribute value in the table. In this case, the conditional operation succeeds only if the comparison evaluates to false. Value and Exists are incompatible with AttributeValueList and ComparisonOperator. Note that if you use both sets of parameters at once, DynamoDB will return a ValidationException exception.

GlobalTable	Represents the properties of a global table.
GlobalTableDescription	Contains details about the global table.
GlobalTableGlobalSecondaryIndexSettingsUpdate	Represents the settings of a global secondary index for a global table that will be modified.
ItemCollectionMetrics	Information about item collections, if any, that were affected by the operation. ItemCollectionMetrics is only returned if the request asked for it. If the table does not have any local secondary indexes, this information is not returned in the response.
ItemResponse	Details for the requested item.
KeySchemaElement	Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index. A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key. A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.
KeysAndAttributes	Represents a set of primary keys and, for each key, the attributes to retrieve from the table. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide the partition key. For a composite primary key, you must provide both the partition key and the sort key.
