Building a Full-Text Search App Using Docker and Elasticsearch

What if your server crashes after you commit to the database, but before you submit to elastic-search? Even if submitting is flawless, this still presents a problem.

Depends on which server :D The Database, ElasticSearch, RabbitMQ, and the application services are on different VMs (in my case, Linodes).

Committing to the database will trigger an entry (via a trigger function) in an audit table. So there is still a record of the transaction. After the system is restored to a healthy state, the next time the sync script is run (either automatically or manually if I'm feeling anxious), it should catch up.

Of course, in a worst-case scenario, I could always rebuild the index :O.

A server crash should be a rare event but if you reindex data regularly, it should not be a huge worry.
