Migrating off of MongoDB to PostgreSQL
Álvaro is a 37 year-old IT entrepreneur, based in Madrid, Spain. Founder and CTO at 8Kdata (www.8kdata.com), a database R&D company, he spends most of his time working on the ToroDB (www.torodb.com) project, the first NoSQL-on-SQL database, a MongoDB-compatible database that runs on top of PostgreSQL.
He is a passionate software developer and open source advocate. Álvaro is a Java software developer, member of JavaSpecialists.eu, but also a DBA, trainer and frequent speaker at international database conferences. He also founded the PostgreSQL Spanish User Group (www.postgrespaña.es), one of the largest PUGs in the world, with more than 700 members.
MongoDB is a successful database in the NoSQL space, mostly used for OLTP-type workloads. However, due to the lack of ACID (transactions in particular) and significant performance issues with OLAP/DW workloads, more and more MongoDB users are considering migrating off of MongoDB to a RDBMS, where PostgreSQL is the usual choice. This represents a significant opportunity for the PostgreSQL ecosystem, to "bring NoSQL to SQL". This talk will present the challenges that MongoDB users are facing and the state of the art of the available tools and open source solutions available to perform ETL and live migrations to PostgreSQL. In particular, ToroDB Stampede will be discussed, an open source solution that replicates live from MongoDB, transform JSON documents into relational tables, and stores the data in PostgreSQL.
