class Aws::GreengrassV2::Types::LambdaExecutionParameters
Contains parameters for a Lambda function that runs on IoT Greengrass.
@note When making an API call, you may pass LambdaExecutionParameters
data as a hash: { event_sources: [ { topic: "TopicString", # required type: "PUB_SUB", # required, accepts PUB_SUB, IOT_CORE }, ], max_queue_size: 1, max_instances_count: 1, max_idle_time_in_seconds: 1, timeout_in_seconds: 1, status_timeout_in_seconds: 1, pinned: false, input_payload_encoding_type: "json", # accepts json, binary exec_args: ["LambdaExecArg"], environment_variables: { "NonEmptyString" => "String", }, linux_process_params: { isolation_mode: "GreengrassContainer", # accepts GreengrassContainer, NoContainer container_params: { memory_size_in_kb: 1, mount_ro_sysfs: false, volumes: [ { source_path: "FileSystemPath", # required destination_path: "FileSystemPath", # required permission: "ro", # accepts ro, rw add_group_owner: false, }, ], devices: [ { path: "FileSystemPath", # required permission: "ro", # accepts ro, rw add_group_owner: false, }, ], }, }, }
@!attribute [rw] event_sources
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. @return [Array<Types::LambdaEventSource>]
@!attribute [rw] max_queue_size
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. @return [Integer]
@!attribute [rw] max_instances_count
The maximum number of instances that a non-pinned Lambda function can run at the same time. @return [Integer]
@!attribute [rw] max_idle_time_in_seconds
The maximum amount of time in seconds that a non-pinned Lambda function can idle before the IoT Greengrass Core software stops its process. @return [Integer]
@!attribute [rw] timeout_in_seconds
The maximum amount of time in seconds that the Lambda function can process a work item. @return [Integer]
@!attribute [rw] status_timeout_in_seconds
The interval in seconds at which a pinned (also known as long-lived) Lambda function component sends status updates to the Lambda manager component. @return [Integer]
@!attribute [rw] pinned
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` @return [Boolean]
@!attribute [rw] input_payload_encoding_type
The encoding type that the Lambda function supports. Default: `json` @return [String]
@!attribute [rw] exec_args
The list of arguments to pass to the Lambda function when it runs. @return [Array<String>]
@!attribute [rw] environment_variables
The map of environment variables that are available to the Lambda function when it runs. @return [Hash<String,String>]
@!attribute [rw] linux_process_params
The parameters for the Linux process that contains the Lambda function. @return [Types::LambdaLinuxProcessParams]
