evidently-sushi

This is a sample for creating a CloudWatch Evidently project.

Preparation

• Install AWS CLI
  • v1: 1.22.16 or higher
  • v2: 2.4.3 or higher

Deploy

via CloudFormation

sh ./cfn/10-evidently.sh 'deploy'

Start Launch

aws evidently start-launch \
--project 'FoodProject' \
--launch 'SushiLaunch'

Simple check with AWS CLI

Project

aws evidently get-project \
--project 'FoodProject'

Feature

aws evidently get-feature \
--project 'FoodProject' \
--feature 'SushiFeature'

Launch

aws evidently get-launch \
--project 'FoodProject' \
--launch 'SushiLaunch'

Evaluate Feature

Run the "evaluate-feature" API 10 times with different EntityIDs.

for i in `seq 10`; do
  aws evidently evaluate-feature \
  --project 'FoodProject' \
  --feature 'SushiFeature' \
  --entity-id "$(date -u +'%s')-${i}" \
  --query 'value.stringValue' \
  --output text
  sleep 1
done

Then you will get the following output.

engawa
engawa
uni
tamago
maguro
maguro
tamago
uni
uni
maguro

If you specify the EntityID set in EntityOverrides, a fixed value will be returned regardless of the percentage of traffic.

for i in `seq 10`; do
  aws evidently evaluate-feature \
  --project 'FoodProject' \
  --feature 'SushiFeature' \
  --entity-id 'shari' \
  --query 'value.stringValue' \
  --output text
done

The output will look like the following

no neta
no neta
no neta
no neta
no neta
no neta
no neta
no neta
no neta
no neta

Start proxy server at local

Start a proxy server in your local environment to run CloudWatch Evidently's EvaluateFeature API.

cd app && go run .

You can get a summary of the Evidently::EvaluateFeature results as a Response by making a request to http://localhost:8080/features/evaluate.

curl 'http://localhost:8080/features/evaluate' | jq .

{
  "entityId": "16c83217c7058878",
  "name": "SushiFeature",
  "reason": "LAUNCH_RULE_MATCH",
  "value": "uni"
}

You can use a fixed EntityID by specifying a specific value for the query parameter entity_id.

curl 'http://localhost:8080/features/evaluate?entity_id=shari' | jq .

{
  "entityId": "shari",
  "name": "SushiFeature",
  "reason": "ENTITY_OVERRIDES_MATCH",
  "value": "no neta"
}
