In 1999, Eric Brewer published the CAP theorem, showing that distributed systems can offer at most two of Consistency, Availability, and Partition tolerance. Apache Cassandra is almost unique among distributed systems in choosing primarily an AP design. In this talk, DataStax co-founder and former Apache Cassandra PMC Chair, Jonathan Ellis, will describe some of the unique challenges in building an AP database, how Cassandra met them, and how those decisions have proven out with time.
