CBPROXY

• Simple proxy that forwards request based on predefined URL's
• The Remote url can be selected with "proxy_condition" in body of request

curl --request GET \
  --url http://localhost:1330/ \
  --header 'content-type: application/json' -v \
  --data '{
    "proxy_condition": "b"
  }'

• CBProxy will find matching URL and proxy the request
• CBproxy implement Circuit breaker(CB) pattern
  • On startup CB will be in closed state and forward all the requests
  • After 3(configurable) consequtive failures CB will change the state to Open and start 20 seconds timer,
  • During this time all requests will fail immideately
  • After 20 seconds timeout , CB will change the state to HalfOpen which will allow single request to pass through
  • If the request successful , it will Close the CB other Open it and start another 20 seconds time cycle

Next steps

• Make the service configurable
  • Move conditions configurations to config
  • Move Circuit breaker configuration to config
  • Move Server startup configuration to config
