Method Details

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 10. If maxBatchingWindow is configured, this value can go up to 10,000.

Default: 10

getEnabled

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

If the SQS event source mapping should be enabled.

Default: true

getFilters

@Stability(Stable)
@Nullable
default List<Map<String,Object>> getFilters()

Add filter criteria option.

Default: - None

getMaxBatchingWindow

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

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

Valid Range: Minimum value of 0 minutes. Maximum value of 5 minutes.

Default: - no batching window. The lambda function will be invoked immediately with the records that are available.

getMaxConcurrency

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

The maximum concurrency setting limits the number of concurrent instances of the function that an Amazon SQS event source can invoke.

Default: - No specific limit.

• https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#events-sqs-max-concurrency Valid Range: Minimum value of 2. Maximum value of 1000.

getReportBatchItemFailures

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

Allow functions to return partially successful responses for a batch of records.

Default: false

builder

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

Returns:

a SqsEventSourceProps.Builder of SqsEventSourceProps
