kruglov-dmitry/akka_http_actor_demo

Example of simple web REST-service on top of akka http with dedicated dispatchers for blocking operations

Requirements

JDK 8 or above SBT 0.13.17

Assumptions

1. username and password ascii strings without special symbols
2. settings of parallelism will be defined by cfg file via deployment section for particular actors
3. API endpoints will receive & return data in plain json format
4. no security

How to build

sbt assembly

will create fat jar with all dependencies at target/scala-2.11/akka_http_actor_demo-assembly-1.0.0.jar

How to run

1. edit cfg file at conf/app.conf
2. execute start.sh by invoking sh start.sh
3. use following endpoints to validate requests:

curl -w "\n" -XGET 'http://localhost:8080/healthcheck'

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"username":"A","password":"A"}' \
  http://localhost:8080/v1/auth

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"username":"B","password":"A"}' \
  http://localhost:8080/v1/auth

curl --header "Content-Type: application/json" \
  --request POST \
  --data '{"username":"B","password":"B"}' \
  http://localhost:8080/v1/auth
  
  curl -v --header "Content-Type: application/json" \
    --request POST \
    --data '{"username":"B"}' \
    http://localhost:8080/v1/auth

If you want to run multiple simultaneous requests you may rely on simple python scripts: by default it send 1k request and print their results

cd load_test
pip install -r requirements.txt
python run_load.py

Notes

NOTE: in case you have encrypted home folder or mounted volume(s) you may need to run following commands before assembling and after every

sbt clean:

rm -rf ./target
mkdir /tmp/`echo $$`
ln -s /tmp/`echo $$` ./target
