§Properties

environmentVariables?: {

[key: string]: string | null | undefined;

} | null

[src]

The map of environment variables that are available to the Lambda function when it runs.

eventSources?: LambdaEventSource[] | null

[src]

The list of event sources to which to subscribe to receive work messages. The Lambda function runs when it receives a message from an event source. You can subscribe this function to local publish/subscribe messages and Amazon Web Services IoT Core MQTT messages.

execArgs?: string[] | null

[src]

The list of arguments to pass to the Lambda function when it runs.

inputPayloadEncodingType?: LambdaInputPayloadEncodingType | null

[src]

The encoding type that the Lambda function supports.

Default: json

linuxProcessParams?: LambdaLinuxProcessParams | null

[src]

The parameters for the Linux process that contains the Lambda function.

maxIdleTimeInSeconds?: number | null

[src]

The maximum amount of time in seconds that a non-pinned Lambda function can idle before the IoT Greengrass Core software stops its process.

maxInstancesCount?: number | null

[src]

The maximum number of instances that a non-pinned Lambda function can run at the same time.

maxQueueSize?: number | null

[src]

The maximum size of the message queue for the Lambda function component. The IoT Greengrass core stores messages in a FIFO (first-in-first-out) queue until it can run the Lambda function to consume each message.

pinned?: boolean | null

[src]

Whether or not the Lambda function is pinned, or long-lived.

A pinned Lambda function starts when IoT Greengrass starts and keeps running in its own container.
A non-pinned Lambda function starts only when it receives a work item and exists after it idles for maxIdleTimeInSeconds. If the function has multiple work items, the IoT Greengrass Core software creates multiple instances of the function.

Default: true

statusTimeoutInSeconds?: number | null

[src]

The interval in seconds at which a pinned (also known as long-lived) Lambda function component sends status updates to the Lambda manager component.

timeoutInSeconds?: number | null

[src]

The maximum amount of time in seconds that the Lambda function can process a work item.
