YSQL Architecture: Implementing Distributed SQL in YugabyteDB

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

  • YugabyteDB has a common distributed storage engine that powers both SQL and NoSQL
  • For supporting NoSQL apps, YugabyteDB is designed for low latency, sub-millisecond reads and massive write scalability. It can handle millions of requests and many TBs of data per node with linear scalability and high resilience.

Introducing YSQL: A PostgreSQL Compatible Distributed SQL API for YugabyteDB

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, YugabyteDB’s PostgreSQL-compatible distributed SQL API, as part of the recent 1.1 release. YSQL (currently in beta) becomes the third member of our multi-API family that previously included two NoSQL APIs,

Google Spanner vs. Calvin: Is There a Clear Winner in the Battle for Global Consistency at Scale?

Prof. Daniel Abadi, lead inventor of the Calvin transaction management protocol and the PACELC theorem, wrote a thought-provoking post last month titled “NewSQL database systems are failing to guarantee consistency, and I blame Spanner”. The post takes a negative view of software-only Google Spanner derivative databases such as YugabyteDB and CockroachDB that use Spanner-like partitioned consensus for single shard transactions and a two phase commit (2PC) protocol for multi-shard (aka distributed) ACID transactions.

YugabyteDB 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),

YugabyteDB 1.1 New Feature: Document Data Modeling with the JSON Data Type

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 document data modeling using the native JSON data type available in YugabyteDB’s Cassandra compatible YCQL API. Note that this data type is specific to YugabyteDB and is not part of the standard Cassandra Query Language (CQL).

With YugabyteDB’s native JSON support,

YugabyteDB 1.1 New Feature: Speeding Up Queries with Secondary Indexes

Welcome to another post from our ongoing series where we highlight a new feature from the latest 1.1 release! Today we are going to look at secondary indexes.

Defining Secondary Indexes

A database index is a data structure that improves the speed of data retrieval operations on a database table. Typically, databases are very efficient at looking up data by the primary key. A secondary index can be created using one or more columns of a database table,

Technical Deep Dive into YugabyteDB 1.1

We announced the general availability of YugabyteDB 1.1 earlier this week. You can download the latest version for your OS or use our default container image as documented in our Quick Start page.

YugabyteDB is an open source database for high performance applications that require ACID transactions and multi-region data distribution. By combining transactional NoSQL and distributed SQL in a single database, YugabyteDB eliminates the need for multiple databases.

YugaByte Database Engineering Update – August 20, 2018

Time for another update from the engineering team at YugaByte! It has been a month since the last update, so let’s dive right in.

Community News

Recent Events

On the conference front, YugaByte was at Google Next towards the end of July. YugabyteDB was already very well integrated into the Google Cloud Compute ecosystem, we additionally announced support for Google Container Engine (GKE). You can also read about how YugabyteDB compares with the various Google Cloud databases.

Understanding How YugabyteDB Runs on Kubernetes

As we reviewed in “Docker, Kubernetes and the Rise of Cloud Native Databases”, Kubernetes has benefited from rapid adoption to become the de-facto choice for container orchestration. This has happened in a short span of only 4 years since Google open sourced the project in 2014. YugabyteDB’s automated sharding and strongly consistent replication architecture lends itself extremely well to containerized deployments powered by Kubernetes orchestration. In this post we’ll look at the various components involved in getting YugabyteDB up and running as Kubernetes StatefulSets.
