Jepsen Testing on YugaByte DB

At YugaByte, our mission is to build a robust, reliable, distributed OLTP database. Needless to say, we take correctness and technical accuracy of our claims very seriously. Therefore, we absolutely love a testing framework like Jepsen which helps verify correctness and are fans of Kyle Kingsbury’s work!

Here is a summary of what we have done so far in regards to Jepsen:

  • We have performed our own DIY style Jepsen testing
  • The YugaByte DB Jepsen testing repository is open source
  • For the current suite of Jepsen tests for YugaByte DB that we have tested in a loop,

Implementing Distributed Transactions the Google Way: Percolator vs. Spanner

Our post 6 Signs You Might be Misunderstanding ACID Transactions in Distributed Databases describes the key challenges involved in building high performance distributed transactions. Multiple open source ACID-compliant distributed databases have started building such transactions by taking inspiration from research papers published by Google. In this post, we dive deeper into Percolator and Spanner, the two Google systems behind those papers,

Docker, Kubernetes and the Rise of Cloud Native Databases

Containerized Stateful Services Are Here

Results from the 2018 Kubernetes Application Usage Survey should put to rest concerns enterprise users have had around the viability of Docker containers and Kubernetes orchestration for running stateful services such as databases and message queues. Its exciting to see that nearly 40% of respondents are running databases (SQL and/or NoSQL) using Kubernetes.

YugaByte DB 1.0 — A Peek Under The Hood

Modern user-facing apps, like E-Commerce and SaaS, frequently require features from multiple databases (broadly — SQL, NoSQL and a cache) to support their multi-workload needs. App developers are responsible for understanding and managing which pieces of data should be stored in which SQL and NoSQL database. Furthermore, the app is also responsible for moving data across the tiers (e.g.

Practical Tradeoffs in Google Cloud Spanner, Azure Cosmos DB and YugaByte DB

Updated April 2019.

The famed CAP Theorem has been a source of much debate among distributed systems engineers. Those of us building distributed databases are often asked how we deal with it. In this post, we dive deeper into the consistency-availability tradeoff imposed by CAP which is only applicable during failure conditions.

YugaByte Has Arrived!

Today, we are launching YugaByte out of stealth and announcing the availability of YugaByte DB’s first public beta release. YugaByte offers an open-source, cloud-native database for mission-critical applications. Yuga in Sanskrit represents an era or an epoch (about 4.32 million human years), a very long period of time. We picked the name YugaByte to signify data that lives forever without limits.
