Method Details

getStartingPosition

@Stability(Stable)
@NotNull
StartingPosition getStartingPosition()

Where to begin consuming the stream.

getBatchSize

@Stability(Stable)
@Nullable
default Number getBatchSize()

The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function.

Your function receives an event with all the retrieved records.

Valid Range:

• Minimum value of 1
• Maximum value of:
  • 1000 for DynamoEventSource
  • 10000 for KinesisEventSource, ManagedKafkaEventSource and SelfManagedKafkaEventSource

Default: 100

getEnabled

@Stability(Stable)
@Nullable
default Boolean getEnabled()

If the stream event source mapping should be enabled.

Default: true

getMaxBatchingWindow

@Stability(Stable)
@Nullable
default Duration getMaxBatchingWindow()

The maximum amount of time to gather records before invoking the function.

Maximum of Duration.minutes(5).

Default: - Duration.seconds(0) for Kinesis, DynamoDB, and SQS event sources, Duration.millis(500) for MSK, self-managed Kafka, and Amazon MQ.

getProvisionedPollerConfig

@Stability(Stable)
@Nullable
default ProvisionedPollerConfig getProvisionedPollerConfig()

Configuration for provisioned pollers that read from the event source.

When specified, allows control over the minimum and maximum number of pollers that can be provisioned to process events from the source.

Default: - no provisioned pollers

builder

@Stability(Stable)
static BaseStreamEventSourceProps.Builder builder()

Returns:

a BaseStreamEventSourceProps.Builder of BaseStreamEventSourceProps
