Epic Event Generator

This is a simple way to generate fake data for comsumption by EpicDB.

Running gen_event once with no arguments will generate a single event and publish it to rabbitmq.

Setup

You'll need to install and start elasticsearch. You'll also need to provide a mapping for the events/card type. Then clone and bundle this repo.

Install and Start elasticsearch

brew update
brew install elasticsearch
elasticsearch --config /usr/local/opt/elasticsearch/config/elasticsearch.yml

By default, elasticsearch is very good at guessing what types you are sending it. But it treats all strings as something you may want to be able to do full text searches on. This is not something that we need for EpicDB, so we are going to help elasticsearch out and define mappings for different types.

For now the only mapping you'll need is the one for the card event type. We can create the events index and define a mapping for cards in one request. If you are using the Elasticsearch marvel plugin, you can copy the first put statement in example_requests/example_request.json Otherwise you can run the following narly command:

curl -XPUT '127.0.0.1:9200/events' -d '{"settings":{"number_of_shards":1,"number_of_replicas":1},"mappings":{"card":{"properties":{"eventTarget":{"type":"string","index":"not_analyzed"},"eventType":{"type":"string","index":"not_analyzed"},"eventTimestamp":{"type":"date"},"eventTrigger":{"type":"nested","properties":{"type":{"type":"string","index":"not_analyzed"},"uuid":{"type":"string","index":"not_analyzed"}}},"data":{"type":"nested","properties":{"uuid":{"type":"string","index":"not_analyzed"},"expiresOn":{"type":"date"},"firstName":{"type":"string","index":"not_analyzed"},"kind":{"type":"string","index":"not_analyzed"},"lastName":{"type":"string","index":"not_analyzed"},"avatar":{"type":"string","index":"not_analyzed"},"birthdate":{"type":"date"},"status":{"type":"string","index":"not_analyzed"}}}}}}}'

Clone repo and bundle

git clone [email protected]:KYCK/epic_event_generator.git
echo ruby-2.1.2 > epic_event_generator/.ruby-version
echo epic_event_generator > epic_event_generator/.ruby-gemset
cd epic_event_generator
bundle

Usage

If you want to generate more than one event, pass the -c options with the number of events you want to publish.

bin/gen_event -c 10 # will generate 10 events
