Properties
Name | Type | Description |
---|---|---|
batch | number | The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. |
enabled? | boolean | If the SQS event source mapping should be enabled. |
filters? | { [string]: any }[] | Add filter criteria option. |
max | Duration | The maximum amount of time to gather records before invoking the function. |
max | number | The maximum concurrency setting limits the number of concurrent instances of the function that an Amazon SQS event source can invoke. |

batchSize?
Type:
number
(optional, default: 10)
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.
enabled?
Type:
boolean
(optional, default: true)
If the SQS event source mapping should be enabled.
filters?
Type:
{ [string]: any }[]
(optional, default: None)
Add filter criteria option.
maxBatchingWindow?
Type:
Duration
(optional, default: no batching window. The lambda function will be invoked immediately with the records that are available.)
The maximum amount of time to gather records before invoking the function.
Valid Range: Minimum value of 0 minutes. Maximum value of 5 minutes.
maxConcurrency?
Type:
number
(optional, default: No specific limit.)
The maximum concurrency setting limits the number of concurrent instances of the function that an Amazon SQS event source can invoke.
