Synopsis
Constructors
DynamoEventSourceProps() |
Properties
BatchSize | The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. |
BisectBatchOnError | If the function returns an error, split the batch in two and retry. |
Enabled | If the stream event source mapping should be enabled. |
MaxBatchingWindow | The maximum amount of time to gather records before invoking the function. |
MaxRecordAge | The maximum age of a record that Lambda sends to a function for processing. |
OnFailure | An Amazon SQS queue or Amazon SNS topic destination for discarded records. |
ParallelizationFactor | The number of batches to process from each shard concurrently. |
ReportBatchItemFailures | Allow functions to return partially successful responses for a batch of records. |
RetryAttempts | Maximum number of retry attempts Valid Range: * Minimum value of 0 * Maximum value of 10000. |
StartingPosition | Where to begin consuming the stream. |
TumblingWindow | The size of the tumbling windows to group records sent to DynamoDB or Kinesis Valid Range: 0 - 15 minutes. |
