6 Technical Challenges Developing a Distributed SQL Database

You can join the discussion on HackerNews here.

We crossed the three year mark of developing YugaByte DB in February of this year. It has been a thrilling journey thus far, but not without its fair share of technical challenges. There were times when we had to go back to the drawing board and even sift through academic research to find a better solution than what we had at hand.

YugaByte DB 1.2 Passes Jepsen Testing

You can join the discussion about the results on HackerNews here.

Last year we published our DIY Jepsen testing results – including the tests and failure modes implemented as well as the bugs found. We recently engaged Kyle Kingsbury, the creator of the Jepsen test suite, for an official analysis and are happy to report that YugaByte DB 1.2 formally passes Jepsen tests using the YCQL API.

Distributed PostgreSQL on a Google Spanner Architecture – Query Layer

Our previous post dived into the details of the storage layer of YugaByte DB called DocDB, a distributed document store inspired by Google Spanner. This post focuses on YugaByte SQL (YSQL), a distributed, highly resilient, PostgreSQL-compatible SQL API layer powered by DocDB. A follow-up post will highlight the challenges faced and lessons learned when engineering such a database.

Distributed PostgreSQL on a Google Spanner Architecture – Storage Layer

In this post, we’ll dive into the architecture of the distributed storage layer of YugaByte DB, which is inspired by Google Spanner’s design. Our subsequent post covers the Query Layer, where the storage layer meets PostgreSQL as the SQL API. Finally, watch for a follow-up post that highlights the lessons we learned while engineering the SQL capabilities of YugaByte DB.

YugaByte DB vs CockroachDB Performance Benchmarks for Internet-Scale Transactional Workloads

Enterprises building cloud native services are gravitating towards transactional NoSQL and globally distributed SQL databases as their next-generation transactional stores. There are at least two distinct usage patterns among these cloud native services – internet-scale transactional workloads and scale-out RDBMS workloads. They have a lot of common demands from the database they use, such as transactions/strong consistency,

YugaByte Database Engineering Update – Nov 27, 2018

Lots has happened since our last engineering update about 3 months ago. Below are some of the highlights.

PostgreSQL API Updates & PostgresConf Silicon Valley Wrap-Up

We have made a lot of progress on YSQL, the PostgreSQL compatible distributed SQL API for YugaByte DB! You can also read about YSQL architecture which covers how distributed SQL is implemented in YugaByte DB.

YSQL Architecture: Implementing Distributed SQL in YugaByte DB

In this post, we will look at the architecture of YSQL, the PostgreSQL-compatible distributed SQL API in YugaByte DB. We will also touch on the current state of the project and the next steps in progress. Here is a quick overview:

  • YugaByte DB has a common distributed storage engine that powers both SQL and NoSQL
  • For supporting NoSQL apps,

Introducing YSQL: A PostgreSQL Compatible Distributed SQL API for YugaByte DB

YugaByte’s mission from day one has been to simplify operational database infrastructure. We are doing so by bringing together the best aspects of SQL and NoSQL into a single transactional, high-performance database. I am pleased to announce a key milestone in our mission with the formal introduction of YSQL, YugaByte DB’s PostgreSQL-compatible distributed SQL API, as part of the recent 1.1 release.

YugaByte DB 1.1 New Feature: Public IPs to Simplify Multi or Hybrid Cloud Database Deployments

Welcome to another post in our ongoing series that highlights new features from the latest 1.1 release announced last week. Today we are going to look at the importance of public IP addresses and hostnames in simplifying multi-cloud and hybrid cloud deployments.

In modern cloud deployments, servers often have a combination of private IP addresses (used in the private LAN and often the IP address of the network interface on the server),
