In the world of PostgreSQL compatible databases, a newcomer is YugabyteDB. Same protocol, similar open-source license, re-using postgres query layer but on a distributed storage plugged in place of heap tables and btree indexes. We will explain the reason for it, why it cannot be just an extension, and why it re-uses PostgreSQL. Similarities and differences, with an overview on the underlying technology: LSM Trees, distributed storage, logical clock, consensus protocols.

The goal is to answer the questions like: - why another database instead of an extension? - when can it can substitute to standard PostgreSQL, and why? - when it is not a good choice and PostgreSQL is the best fit? - what is distributed vs. sharding when it comes to scale-out?
