Joram Barrez, a software engineer and tech blogger, explores the integration of Flowable with CockroachDB, an open-source database system that is Apache 2 licensed and noteworthy for its horizontal scalability, SQL support through the Postgres wire protocol, and full ACID semantics with distributed transactions. Despite being in early stages with some features still unoptimized, CockroachDB's recent addition of basic support for joins prompted Barrez to experiment with running the Flowable v6 process engine on it. He highlights the database's resilience, likening it to the cockroach's ability to survive extreme conditions, and encourages readers to explore the technical details on the CockroachLabs blog, while acknowledging the complexity involved in understanding distributed systems and the CAP theorem, specifically CockroachDB's classification as a CP system.
