» aws_lambda_event_source_mapping

Provides a Lambda event source mapping. This allows Lambda functions to get events from Kinesis and DynamoDB.

For information about Lambda and how to use it, see What is AWS Lambda? For information about event source mappings, see CreateEventSourceMapping in the API docs.

» Example Usage

resource "aws_lambda_event_source_mapping" "event_source_mapping" {
  batch_size        = 100
  event_source_arn  = "arn:aws:kinesis:REGION:123456789012:stream/stream_name"
  enabled           = true
  function_name     = "arn:aws:lambda:REGION:123456789012:function:function_name"
  starting_position = "TRIM_HORIZON|LATEST"
}

» Argument Reference

  • batch_size - (Optional) The largest number of records that Lambda will retrieve from your event source at the time of invocation. Defaults to 100.
  • event_source_arn - (Required) The event source ARN - can either be a Kinesis or DynamoDB stream.
  • enabled - (Optional) Determines if the mapping will be enabled on creation. Defaults to true.
  • function_name - (Required) The name or the ARN of the Lambda function that will be subscribing to events.
  • starting_position - (Required) The position in the stream where AWS Lambda should start reading. Can be one of either TRIM_HORIZON or LATEST.

» Attributes Reference

  • function_arn - The the ARN of the Lambda function the event source mapping is sending events to. (Note: this is a computed value that differs from function_name above.)
  • last_modified - The date this resource was last modified.
  • last_processing_result - The result of the last AWS Lambda invocation of your Lambda function.
  • state - The state of the event source mapping.
  • state_transition_reason - The reason the event source mapping is in its current state.
  • uuid - The UUID of the created event source mapping.

» Import

Lambda Event Source Mappings can be imported using the UUID (event source mapping identifier), e.g.

$ terraform import aws_lambda_event_source_mapping.event_source_mapping 12345kxodurf3443
