# Lambda parameters for Amazon SQS event source mappings
Parameters

All Lambda event source types share the same [CreateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_CreateEventSourceMapping.html) and [UpdateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_UpdateEventSourceMapping.html) API operations. However, only some of the parameters apply to Amazon SQS.


| Parameter | Required | Default | Notes | 
| --- | --- | --- | --- | 
|  BatchSize  |  N  |  10  |  For standard queues, the maximum is 10,000. For FIFO queues, the maximum is 10.  | 
|  Enabled  |  N  |  true  | none  | 
|  EventSourceArn  |  Y  | N/A |  The ARN of the data stream or a stream consumer  | 
|  FunctionName  |  Y  | N/A  | none  | 
|  FilterCriteria  |  N  |  N/A   |  [Control which events Lambda sends to your function](invocation-eventfiltering.md)  | 
|  FunctionResponseTypes  |  N  | N/A  |  To let your function report specific failures in a batch, include the value `ReportBatchItemFailures` in `FunctionResponseTypes`. For more information, see [Implementing partial batch responses](services-sqs-errorhandling.md#services-sqs-batchfailurereporting).  | 
|  MaximumBatchingWindowInSeconds  |  N  |  0  | Batching window is not supported for FIFO queues | 
|  ProvisionedPollerConfig  |  N  |  N/A  |  Configures the minimum (2-200) and maximum (2-2000) number of dedicated event pollers for the SQS event source mapping. Each poller can handle up to 1 MB/sec of throughput and 10 concurrent invokes.  | 
|  ScalingConfig  |  N  |  N/A   |  [Configuring maximum concurrency for Amazon SQS event sources](services-sqs-scaling.md#events-sqs-max-concurrency)  |
