Marios Trivyzas, Senior Core Engineer,

A Database Month event

This is the dark and terrible tale of a migration from an relational SQL database, an RDBMS like Oracle or Postgres, to NoSQL with MongoDB. The battles were fought by those unwilling or unable to learn Mongo's query language. The trials we faced feeding Mongo back through a SQL data warehouse. The tears shed. The lives lost (well, virtual-lives lost, lol.)

In this session, we will look at how using a scalable SQL database with full text search would have solved all of the most-challenging aspects of SQL-to-NoSQL migration.
