Mixed and Verified Consistency with Propel and ConOpY

Explore mixed consistency in distributed systems and verified Conflict-free Replicated Data Types (CRDTs) in this conference talk. Dive into ConOpY, an object-oriented language supporting mixed consistent replication, and learn how its type system ensures static reasoning about consistency. Discover Propel, the first type system capturing algebraic properties required for correct CRDT implementation. Understand how Propel's Scala embedding enables automatic deduction of properties for state-based CRDTs and its potential for verifying op-based CRDTs. Gain insights into the challenges of managing consistency in replicated data and the innovative solutions presented to address these issues in distributed system programming.
