Class TransactionCanceledException

Namespace
Amazon.DynamoDBv2.Model
Assembly
AWSSDK.DynamoDBv2.dll

The entire transaction request was canceled.

DynamoDB cancels a 

TransactWriteItems
request under the following circumstances:

  • A condition in one of the condition expressions is not met.

  • A table in the 

    TransactWriteItems
    request is in a different account or region.

  • More than one action in the 

    TransactWriteItems
    operation targets the same item.

  • There is insufficient provisioned capacity for the transaction to be completed.

  • An item size becomes too large (larger than 400 KB), or a local secondary index (LSI) becomes too large, or a similar validation error occurs because of changes made by the transaction.

  • There is a user error, such as an invalid data format.

DynamoDB cancels a 

TransactGetItems
request under the following circumstances:

  • There is an ongoing 

    TransactGetItems
    operation that conflicts with a concurrent 
    PutItem
    , 
    UpdateItem
    , 
    DeleteItem
    or 
    TransactWriteItems
    request. In this case the 
    TransactGetItems
    operation fails with a 
    TransactionCanceledException
    .

  • A table in the 

    TransactGetItems
    request is in a different account or region.

  • There is insufficient provisioned capacity for the transaction to be completed.

  • There is a user error, such as an invalid data format.

note

If using Java, DynamoDB lists the cancellation reasons on the 

CancellationReasons
property. This property is not set for other languages. Transaction cancellation reasons are ordered in the order of requested items, if an item has no error it will have 
None
code and 
Null
message.

Cancellation reason codes and possible error messages:

  • No Errors:

    • Code: 

      None

    • Message: 

      null

  • Conditional Check Failed:

    • Code: 

      ConditionalCheckFailed

    • Message: The conditional request failed.

  • Item Collection Size Limit Exceeded:

    • Code: 

      ItemCollectionSizeLimitExceeded

    • Message: Collection size exceeded.

  • Transaction Conflict:

    • Code: 

      TransactionConflict

  • Provisioned Throughput Exceeded:

    • Code:

  • Throttling Error:

    • Code: 

      ThrottlingError

    • Messages:

      • Throughput exceeds the current capacity of your table or index. DynamoDB is automatically scaling your table or index so please try again shortly. If exceptions persist, check if you have a hot key: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-design.html.

        note

        This message is returned when writes get throttled on an On-Demand table as DynamoDB is automatically scaling the table.
