RethinkDB as a distributed open source database

Summary

After three years of development, the RethinkDB team releases a distributed database with manageable replication and an expressive query language. RethinkDB was released publicly in November 2012. The project is developed as free software.

Ideas

  • Replication distributes data across several independent servers.
  • Sharding splits tables across machines and disks.
  • A web interface shows the cluster state and running queries.
  • The query language combines functional operators into understandable data flows.

Insights

  • Distributed databases need usable operating tools as well as correct algorithms.
  • Replication increases availability and creates new consistency decisions.
  • Open development makes architectural decisions and bugs publicly reviewable.

Facts

  • The database supports replication and horizontal partitioning.

Recommendations

  • Test node loss and recovery under realistic load.
  • Monitor replication lag and unevenly distributed shards.
