validation-server-backend

AWS Lambda function for the validation server back-end. The lambda function accepts an event payload that includes the transformation query, analysis query, and the epsilon level at which to run the analysis query.

Validation Server Whitepaper

deploy

Run sam package locally as a workaround since CodeBuild fails for no clear reason.

ACCOUNT_ID=$(aws sts get-caller-identity | jq ".Account" | sed 's/\"//g')
S3_BUCKET=aws-codestar-us-east-1-672001523455-validation-serv-pipe
sam build
sam package --s3-bucket $S3_BUCKET --output-template-file template-export.yml --image-repository ${ACCOUNT_ID}.dkr.ecr.us-east-1.amazonaws.com/validation-server-engine

Then commit the new template-export up to GitHub.
