terraform-aws-lambda-event-source-mapping

Terraform module that creates Lambda functions of event source mapping in AWS of type DynamoDB, SQS and Kinesis.

• Required Modules :
  • Module Lambda-Function
  • Module DynamoDB

Usage

module "lambda_mapping_dynamodb_dev" {
  source            = "./modules/terraform-aws-lambda-event-source-mapping"
  batch_size        = "${var.batch_size}"
  event_source_arn  = "${module.dynamo-table-dev.stream_arn}"
  function_name     = "${module.lambda-function.arn}"
  starting_position = "${var.starting_position}"
  enabled           = "${var.enabled}"
  has_dynamodb      = "true"
}

module "lambda_mapping_dynamodb_prod" {
  source            = "./modules/terraform-aws-lambda-event-source-mapping"
  batch_size        = "${var.batch_size}"
  event_source_arn  = "${module.dynamo-table-prod.stream_arn}"
  function_name     = "${module.lambda-function.arn}"
  starting_position = "${var.starting_position}"
  enabled           = "${var.enabled}"
  has_dynamodb      = "true"
}

Inputs

Name	Description	Type	Default	Required
batch_size	The largest number of records that Lambda will retrieve from your event source at the time of invocation. Defaults to 100 for DynamoDB and Kinesis, 10 for SQS.	string	""	no
enabled	Determines if the mapping will be enabled on creation. Defaults to true.	string	"true"	no
event_source_arn	he event source ARN - can either be a Kinesis or DynamoDB stream	string	n/a	yes
function_name	The name or the ARN of the Lambda function that will be subscribing to events.	string	n/a	yes
has_dynamodb	true or false	string	"false"	no
has_kinesis	true or false	string	"false"	no
has_sqs	true or false	string	"false"	no
starting_position	The position in the stream where AWS Lambda should start reading. Must be one of AT_TIMESTAMP (Kinesis only), LATEST or TRIM_HORIZON if getting events from Kinesis or DynamoDB. Must not be provided if getting events from SQS.	string	""	no
starting_position_timestamp	A timestamp in RFC3339 format of the data record which to start reading when using starting_position set to AT_TIMESTAMP. If a record with this exact timestamp does not exist, the next later record is chosen. If the timestamp is older than the current trim horizon, the oldest available record is chosen.	string	""	no
