# Data Types The Amazon Keyspaces API contains several data types that various actions use. This section describes each data type in detail. **Note** The order of each element in a data type structure is not guaranteed. Applications should not assume a particular order. The following data types are supported: + [AutoScalingPolicy](API_AutoScalingPolicy.md) + [AutoScalingSettings](API_AutoScalingSettings.md) + [AutoScalingSpecification](API_AutoScalingSpecification.md) + [CapacitySpecification](API_CapacitySpecification.md) + [CapacitySpecificationSummary](API_CapacitySpecificationSummary.md) + [CdcSpecification](API_CdcSpecification.md) + [CdcSpecificationSummary](API_CdcSpecificationSummary.md) + [ClientSideTimestamps](API_ClientSideTimestamps.md) + [ClusteringKey](API_ClusteringKey.md) + [ColumnDefinition](API_ColumnDefinition.md) + [Comment](API_Comment.md) + [EncryptionSpecification](API_EncryptionSpecification.md) + [FieldDefinition](API_FieldDefinition.md) + [KeyspaceSummary](API_KeyspaceSummary.md) + [PartitionKey](API_PartitionKey.md) + [PointInTimeRecovery](API_PointInTimeRecovery.md) + [PointInTimeRecoverySummary](API_PointInTimeRecoverySummary.md) + [ReplicaAutoScalingSpecification](API_ReplicaAutoScalingSpecification.md) + [ReplicaSpecification](API_ReplicaSpecification.md) + [ReplicaSpecificationSummary](API_ReplicaSpecificationSummary.md) + [ReplicationGroupStatus](API_ReplicationGroupStatus.md) + [ReplicationSpecification](API_ReplicationSpecification.md) + [SchemaDefinition](API_SchemaDefinition.md) + [StaticColumn](API_StaticColumn.md) + [TableSummary](API_TableSummary.md) + [Tag](API_Tag.md) + [TargetTrackingScalingPolicyConfiguration](API_TargetTrackingScalingPolicyConfiguration.md) + [TimeToLive](API_TimeToLive.md) + [WarmThroughputSpecification](API_WarmThroughputSpecification.md) + [WarmThroughputSpecificationSummary](API_WarmThroughputSpecificationSummary.md)
