ScyllaDB is an open-source distributed NoSQL data store, reimplemented from the popular Apache Cassandra database. Released just four years ago in 2015, Scylla has averaged over 220% year-over-year growth in popularity according to DB-Engines. We’ve heard a lot about this rising database from the DBA community and our users, and decided to become a sponsor for this years Scylla Summit to learn more about the deployment trends from its users.

TLA+ model checking made symbolic Konnov et al., OOPSLA’19. TLA+ is a formal specification language ( T emporal L ogic of A ctions) particularly well suited to reasoning about distributed algorithms. In addition to the specification language, the TLA+ toolset includes a model checker (TLC) and a theorem prover (TLAPS). Given the huge state spaces involved in many real-world settings, the TLC model checker can take a long time / a lot of resources to run.

EventStorming is a hugely popular technique, allowing us to explore, analyse, and model business domains more effectively than traditional techniques. The result is that we create better designed software systems and teams of problem solvers rather than order takers. Used judiciously, EventStorming gives us the ability to uncover enough information about our domain and our business that we can use it to design our microservices, bounded contexts, and even our teams.

Mergeable replicated data types Kaki et al., OOPSLA’19. This paper was published at OOPSLA, but perhaps it’s amongst the distributed systems community that I expect there to be the greatest interest. Mergeable Replicated Data Types (MRDTs) are in the same spirit as CRDTs but with the very interesting property that they compose. Furthermore, a principled approach for deriving MRDTs is provided, allowing a wide range of data-types to be lifted to their mergeable, replicated counterparts with

Mergeable replicated data types – part II Kaki et al., OOPLSA ’19. Last time out we saw how Mergeable Replicated Data Types (MRDTs) use a bijection between the natural domain of a data type and relational sets to define merge semantics between two concurrently modified versions given their lowest common ancestor (LCA). Today we’re picking things up in §4 of the paper, starting with how to derive a merge function for an arbitrary data type.

In today’s increasingly complex environments, it’s simply impossible for a human operator to manually follow the highly dynamic nature of transactions within microservices and serverless functions. Even the best baseline approaches come with a tiny percentage of false-positive alerts, the number being directly proportional to the number of components you’re monitoring.
