# Supported Lambda blueprints
<a name="lambda-blueprints"></a>

These blueprints demonstrate how you can create and use Amazon Lambda functions to transform data in your Amazon Data Firehose data streams. 

**To see the blueprints that are available in the Amazon Lambda console**

1. Sign in to the Amazon Web Services Management Console and open the Amazon Lambda console at [https://console.amazonaws.cn/lambda/](https://console.amazonaws.cn/lambda/).

1. Choose **Create function**, and then choose **Use a blueprint**.

1. In the **Blueprints** field, search for the keyword `firehose` to find the Amazon Data Firehose Lambda blueprints.

List of blueprints:
+ **Process records sent to Amazon Data Firehose stream (Node.js, Python)**

  This blueprint shows a basic example of how to process data in your Firehose data stream using Amazon Lambda. 

  *Latest release date:* November, 2016. 

  *Release notes:* none.
+ **Process CloudWatch Logs sent to Firehose **

  This blueprint is deprecated. Do not use this blueprint. It might incur high charges when the decompressed CloudWatch Logs data is more than 6MB (Lambda limit). For information on processing CloudWatch Logs sent to Firehose, see [Writing to Firehose Using CloudWatch Logs](https://docs.amazonaws.cn/firehose/latest/dev/writing-with-cloudwatch-logs.html).
+ **Convert Amazon Data Firehose stream records in syslog format to JSON (Node.js)**

  This blueprint shows how you can convert input records in RFC3164 Syslog format to JSON.

1. Go to [Amazon Serverless Application Repository](https://aws.amazon.com/serverless/serverlessrepo).

1. Choose **Browse all applications**.

1. In the **Applications** field, search for the keyword `firehose`.

You can also create a Lambda function without using a blueprint. See [Getting Started with Amazon Lambda](https://docs.aws.amazon.com/lambda/latest/dg/getting-started.html).
