Gets and sets the property Runtime.The runtime environment for the Lambda function you are uploading. To use the Python runtime v3.6, set the value to "python3.6". To use the Python runtime v2.7, set the value to "python2.7". To use the Node.js runtime v6.10, set the value to "nodejs6.10". To use the Node.js runtime v4.3, set the value to "nodejs4.3". Node v0.10.42 is currently marked as deprecated. You must migrate existing functions to the newer Node.js runtime versions available on AWS Lambda (nodejs4.3 or nodejs6.10) as soon as possible. You can request a one-time extension until June 30, 2017 by going to the Lambda console and following the instructions provided. Failure to do so will result in an invalid parmaeter error being returned. Note that you will have to follow this procedure for each region that contains functions written in the Node v0.10.42 runtime.
