Conecting AWS Lambda to Redshift - Times out after 60 seconds

Question

I created an AWS Lambda function that:

• logs onto Redshift via JDBC URL
• runs a query

Locally, using Node, I can successfully connect to

Answer 1

If you are using serverless-framework v1.5.0, you should add:

iamRoleStatements: - Effect: Allow Action: - ec2:CreateNetworkInterface Resource: '*' - Effect: Allow Action: - ec2:DeleteNetworkInterface - ec2:DescribeNetworkInterfaces Resource: 'arn:aws:ec2:${self:provider.region}:*:network-interface/*'

Also should add all securityGroupIds to Inbounds Rules, like below:

Answer 2

I find it's either you open your Redshift security group public to all sources, or none. Because a Lambda function isn't running on a fixed address or even a fixed range of IP addresses, which is completely transparent to users (AKA server-less).

I just saw Amazon announced the new Lambda feature to support VPC yesterday. I guess if we can run a Redshift cluster in a VPC, this could solve the problem.
