Robert Blumen talks with Eric Brewer, who
discovered the CAP (consistency, availability, partition
tolerance) theorem. The first part of the show focuses on
Brewer's original thesis presented at the 2000 ACM Symposium on
Principles of Distributed Computing (PODC): What set of problems
motivated the formulation of CAP? How was it understood at the
time? What are the three types of systems that can exist (or are
there only two types)? Is latency the same as a partition? The
second half of the show covers Brewer's more recent retrospective
article on how things have changed since then: What major
insights about CAP have emerged? How has CAP impacted the
architecture of real applications? How can architects use the
full space of the CAP theorem to arrive at the best designs? Are
some types of systems more CAP-friendly? How do CAP systems
recover when partitions are healed? The show wraps up with some
speculation about the next 16 years.
