Types

type AttributeValue

type AttributeValue interface {
	// contains filtered or unexported methods
}

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 (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html#HowItWorks.DataTypes) in the Amazon DynamoDB Developer Guide.

The following types satisfy this interface:

AttributeValueMemberB
AttributeValueMemberBOOL
AttributeValueMemberBS
AttributeValueMemberL
AttributeValueMemberM
AttributeValueMemberN
AttributeValueMemberNS
AttributeValueMemberNULL
AttributeValueMemberS
AttributeValueMemberSS
Example (OutputUsage)
// Code generated by smithy-go-codegen DO NOT EDIT.

package main

import (
	"fmt"
	"github.com/aws/aws-sdk-go-v2/service/dynamodbstreams/types"
)

func main() {
	var union types.AttributeValue
	// type switches can be used to check the union value
	switch v := union.(type) {
	case *types.AttributeValueMemberB:
		_ = v.Value // Value is []byte

	case *types.AttributeValueMemberBOOL:
		_ = v.Value // Value is bool

	case *types.AttributeValueMemberBS:

type KeySchemaElement

type KeySchemaElement struct {

	// The name of a key attribute.
	//
	// This member is required.
	AttributeName *string

	// The role that this key attribute will assume:
	//   - HASH - partition key
	//   - RANGE - sort key
	// The partition key of an item is also known as its hash attribute. The term
	// "hash attribute" derives from DynamoDB's usage of an internal hash function to
	// evenly distribute data items across partitions, based on their partition key
	// values. The sort key of an item is also known as its range attribute. The term
	// "range attribute" derives from the way DynamoDB stores items with the same
	// partition key physically close together, in sorted order by the sort key value.
	//
	// This member is required.
	KeyType KeyType
	// contains filtered or unexported fields
}

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.

type KeyType

type KeyType string
const (
	KeyTypeHash  KeyType = "HASH"
	KeyTypeRange KeyType = "RANGE"
)

Enum values for KeyType

func (KeyType) Values added in v0.29.0

func (KeyType) Values() []KeyType

Values returns all known values for KeyType. Note that this can be expanded in the future, and so it is only as up to date as the client. The ordering of this slice is not guaranteed to be stable across updates.

type LimitExceededException

type LimitExceededException struct {
	Message *string

	ErrorCodeOverride *string
	// contains filtered or unexported fields
}

There is no limit to the number of daily on-demand backups that can be taken. For most purposes, up to 500 simultaneous table operations are allowed per account. These operations include CreateTable , UpdateTable , DeleteTable , UpdateTimeToLive , RestoreTableFromBackup , and RestoreTableToPointInTime . When you are creating a table with one or more secondary indexes, you can have up to 250 such requests running at a time. However, if the table or index specifications are complex, then DynamoDB might temporarily reduce the number of concurrent operations. When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account. There is a soft account quota of 2,500 tables. GetRecords was called with a value of more than 1000 for the limit request parameter. More than 2 processes are reading from the same streams shard at the same time. Exceeding this limit may result in request throttling.

type TrimmedDataAccessException

type TrimmedDataAccessException struct {

}

The operation attempted to read past the oldest stream record in a shard. In DynamoDB Streams, there is a 24 hour limit on data retention. Stream records whose age exceeds this limit are subject to removal (trimming) from the stream. You might receive a TrimmedDataAccessException if:

  • You request a shard iterator with a sequence number older than the trim point (24 hours).
  • You obtain a shard iterator, but before you use the iterator in a GetRecords request, a stream record in the shard exceeds the 24 hour period and is trimmed. This causes the iterator to access a record that no longer exists.
