Build Amazon Lambda functions using Amazon Timestream for LiveAnalytics with Python

To build Amazon Lambda functions using Amazon Timestream for LiveAnalytics with Python, follow the steps below.

  1. Create an IAM role for Lambda to assume that will grant the required permissions to access the Timestream Service, as outlined in Provide Timestream for LiveAnalytics access.

  2. Edit the trust relationship of the IAM role to add Lambda service. You can use the commands below to update an existing role so that Amazon Lambda can assume it:

    1. Create the trust policy document:

      cat > Lambda-Role-Trust-Policy.json << EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": [
          "lambda.amazonaws.com"
        ]
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
EOF

    2. Update the role from previous step with the trust document

      aws iam update-assume-role-policy --role-name <name_of_the_role_from_step_1> --policy-document file://Lambda-Role-Trust-Policy.json
