goworker-examples

These are examples of goworker workers.

To benchmark them yourself, run

redis-cli -r 100 RPUSH resque:queue:hello '{"class":"Hello","args":[]}'
redis-cli -r 100 RPUSH resque:queue:insert '{"class":"Insert","args":["John Doe","jdoe@example.com","(555) 555-5555"]}'
redis-cli -r 100 RPUSH resque:queue:multiply '{"class":"Multiply","args":[]}'
redis-cli -r 100 RPUSH resque:queue:sleep '{"class":"Sleep","args":[1]}'

export DATABASE_URL=postgres://goworker:goworker@localhost:5432/goworker_development

go get github.com/benmanns/goworker-examples
time $GOPATH/bin/goworker-examples -queues=hello,insert,multiply,sleep -exit-on-complete=true

This app requires a local Postgres database. See the above DATABASE_URL configuration string for more information.

Running on Heroku

These examples will run on Heroku.

First, clone the examples.

git clone https://github.com/benmanns/goworker-examples.git myapp
cd myapp

Then, create an app with the go buildpack.

heroku create -b https://github.com/kr/heroku-buildpack-go

Next, install the redistogo:nano and heroku-postgresql:dev addons (both free).

heroku addons:add redistogo:nano
heroku addons:add heroku-postgresql:dev

Promote your Redis and Postgres databases. Be sure to change [COLOR] to whatever was provided by the heroku-postgresql:dev addon.

heroku config:set REDIS_PROVIDER=REDISTOGO_URL
heroku pg:promote HEROKU_POSTGRESQL_[COLOR]_URL

Configure the goworker process with environment variables. See the Procfile for more information.

heroku config:set \
  QUEUES=hello,insert,multiply,sleep \
  INTERVAL=1.0 \
  CONCURRENCY=50 \
  CONNECTIONS=2

Finally, push and start your workers.

git push heroku master
heroku ps:scale worker=1
