Thoth demo

Get started

• Clone the demo project

git clone https://github.com/trulia/thoth-demo.git

Start the demos

This example contains a demo version of

• ActiveMQ broker
• A simple solr instance that we will use to intercept queries from
• A thoth index
• Thoth

Start the demos separately or use the example start script

• Execute start_demo.sh .

  ./scripts/start_demo.sh
  

  Access to activemq webUI will be on default port 8161 , if user and password requested use user:admin , password:admin

  Access to demo solr instance will be on port 8900

  Access to demo thoth index will be on port 8983

  Thoth will be running on port 8081

Demo of the functionality

• Let's execute some queries and simulate some exceptions from the intercepted instance

   # Standard query *:*
   curl 'http://localhost:8900/solr/collection1/select?q=*%3A*&wt=json&indent=true'
  
   # Query that will generate exception
   curl 'http://localhost:8900/solr/collection1/select?q=THIS_FIELD:DOES_NOT_EXIST&wt=json&indent=true'
  

• Those requests have been intercepted and indexed by Thoth inside the Thoth index . Let's verify this:

http://localhost:8983/solr/collection1/select?q=*%3A*&wt=json&indent=true

• After a minute the documents will be automatically shrinked and a summary shrank document will be added to the shrank core. You can change the shrinking configuration inside thoth/resources/application.properties

Here's a snippet

# Enable/Disable shrinking feature
thoth.shrinker.enabled=true

# Schedule when do you want the shrinker feature to be triggered
# 0 * * * * ? --> Every minute
thoth.shrinker.schedule=0 * * * * ?
# 'how long back' you want to shrink docs in seconds
thoth.shrinker.period= 900
thoth.shrinker.threadPoolSize = 1

Stop the Demos

The stop_demo.sh script kills the above started process based on the default port number's.

Stop the demos separately or use the example stop script. (Make sure you have execute permission's)

• Execute stop_demo.sh .

  ./scripts/stop_demo.sh
