The sequence number of a stream record in the shard from which to start reading.

The Amazon Resource Name (ARN) for the stream.

The identifier of the shard. The iterator will be returned for this shard ID.

Determines how the shard iterator is used to start reading stream records from the shard:

• AT_SEQUENCE_NUMBER - Start reading exactly from the position denoted by a specific sequence number.
• AFTER_SEQUENCE_NUMBER - Start reading right after the position denoted by a specific sequence number.
• TRIM_HORIZON - Start reading at the last (untrimmed) stream record, which is the oldest record in the 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.
• LATEST - Start reading just after the most recent stream record in the shard, so that you always read the most recent data in the shard.

The position in the shard from which to start reading stream records sequentially. A shard iterator specifies this position using the sequence number of a stream record in a shard.

The response's http status code.

The maximum number of records to return from the shard. The upper limit is 1000.

A shard iterator that was retrieved from a previous GetShardIterator operation. This iterator can be used to access the stream records in this shard.

The stream records from the shard, which were retrieved using the shard iterator.

The next position in the shard from which to start sequentially reading stream records. If set to null, the shard has been closed and the requested iterator will not return any more data.

The response's http status code.

The ARN (Amazon Resource Name) of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedStreamArn in the previous operation.

The maximum number of streams to return. The upper limit is 100.

If this parameter is provided, then only the streams associated with this table name are returned.

The stream ARN of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedStreamArn is empty, then the "last page" of results has been processed and there is no more data to be retrieved.

If LastEvaluatedStreamArn is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedStreamArn is empty.

A list of stream descriptors associated with the current account and endpoint.

The response's http status code.

The shard ID of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedShardId in the previous operation.

The maximum number of shard objects to return. The upper limit is 100.

The Amazon Resource Name (ARN) for the stream.

A complete description of the stream, including its creation date and time, the DynamoDB table associated with the stream, the shard IDs within the stream, and the beginning and ending sequence numbers of stream records within the shards.

An attribute of type List. For example:

"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]

An attribute of type Number Set. For example:

"NS": ["42.2", "-19", "7.5", "3.14"]

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

An attribute of type Map. For example:

"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}

An attribute of type Null. For example:

"NULL": true

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

An attribute of type Binary Set. For example:

"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

An attribute of type String Set. For example:

"SS": ["Giraffe", "Hippo" ,"Zebra"]

An attribute of type String. For example:

"S": "Hello"

An attribute of type Boolean. For example:

"BOOL": true

A unique identifier for the entity that made the call. For Time To Live, the principalId is "dynamodb.amazonaws.com".

The type of the identity. For Time To Live, the type is "Service".

The name of a key attribute.

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.

Items that are deleted by the Time to Live process after expiration have the following fields:

• Records[].userIdentity.type

  "Service"

• Records[].userIdentity.principalId

  "dynamodb.amazonaws.com"

The version number of the stream record format. This number is updated whenever the structure of Record is modified.

Client applications must not assume that eventVersion will remain at a particular value, as this number is subject to change at any time. In general, eventVersion will only increase as the low-level DynamoDB Streams API evolves.

The main body of the stream record, containing all of the DynamoDB-specific fields.

The region in which the GetRecords request was received.

The type of data modification that was performed on the DynamoDB table:

• INSERT - a new item was added to the table.
• MODIFY - one or more of an existing item's attributes were modified.
• REMOVE - the item was deleted from the table

The AWS service from which the stream record originated. For DynamoDB Streams, this is aws:dynamodb.

A globally unique identifier for the event that was recorded in this stream record.

The first sequence number for the stream records contained within a shard. String contains numeric characters only.

The last sequence number for the stream records contained within a shard. String contains numeric characters only.

The shard ID of the current shard's parent.

The range of possible sequence numbers for the shard.

The system-generated identifier for this shard.

A timestamp, in ISO 8601 format, for this stream.

Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

• the AWS customer ID.
• the table name
• the StreamLabel

The Amazon Resource Name (ARN) for the stream.

The DynamoDB table with which the stream is associated.

The shard ID of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedShardId is empty, then the "last page" of results has been processed and there is currently no more data to be retrieved.

If LastEvaluatedShardId is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedShardId is empty.

A timestamp, in ISO 8601 format, for this stream.

Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:

• the AWS customer ID.
• the table name
• the StreamLabel

Indicates the current status of the stream:

• ENABLING - Streams is currently being enabled on the DynamoDB table.
• ENABLED - the stream is enabled.
• DISABLING - Streams is currently being disabled on the DynamoDB table.
• DISABLED - the stream is disabled.

The key attribute(s) of the stream's DynamoDB table.

Indicates the format of the records within this stream:

• KEYS_ONLY - only the key attributes of items that were modified in the DynamoDB table.
• NEW_IMAGE - entire items from the table, as they appeared after they were modified.
• OLD_IMAGE - entire items from the table, as they appeared before they were modified.
• NEW_AND_OLD_IMAGES - both the new and the old images of the items from the table.
