YugabyteDB is a high-performance distributed SQL database for cloud-native applications, developed by Yugabyte.^[1]

History

Yugabyte was founded by ex-Facebook engineers Kannan Muthukkaruppan, Karthik Ranganathan, and Mikhail Bautin. At Facebook, they were part of the team that built and operated Cassandra and HBase^[2]. The team scaled the data platform for massive real-time workloads such as Facebook Messenger and Facebook’s Operational Data Store from millions to billions of users in just a few years^[3].

The founders came together in February 2016 to build YugabyteDB, believing that the trends they experienced at Facebook – microservices, containerization, high availability, geographic distribution, APIs, and open-source – were relevant to all businesses, especially as they move from on-premise to cloud-native operations^[4].

YugabyteDB was initially available in two editions: community and enterprise. In July 2019, Yugabyte open sourced previously commercial features and launched YugabyteDB as 100% open-source under the Apache 2.0 license.

The rapid evolution of the product led to being named as a 2020 Gartner Cool Vendor in Data Management^[5].

Yugabyte launched Yugabyte Cloud, a fully managed database-as-a-service offering of YugabyteDB, in September 2021^[6]. Yugabyte Cloud combines the power of distributed SQL with the ease of use of a cloud database management system.

Yugabyte closed a $188 Million Series C funding round on October 28, 2021, bringing their valuation to over $1.3bn^[7]. The round was led by Sapphire Ventures, and included participation from Alkeon Capital, Meritech Capital Partners, and Wells Fargo Strategic Capital, and existing investors Lightspeed Venture Partners, 8VC, Dell Technologies Capital, Wipro Ventures.

Features

YugabyteDB has the following key features

Horizontally scaling from 3 nodes upward
Deploy a database instance across multiple failure zones (rack, availability zone, cloud region) in order to survive an outage at the failure zone level
Enterprise-grade security for Data at rest, Data in motion, Field-level encryption, Authentication, and Authorisation as well as appropriate audit logging
Code compatibility with PostgreSQL by reusing PostgreSQL’s query layer to achieve a high degree of compatibility with existing PostgreSQL applications including triggers, functions, stored procedures, strong secondary indexes, and distributed ACID transactions.
Geo-placement of data - the ability to limit data to a given location or set of locations
Asynchronous replication between database instances

Architecture

YugabyteDB is a Distributed SQL database that is strongly transactionally consistent across failure zones (i.e. ACID compliance] as demonstrated by Jepsen testing^[8]. In CAP Theorem terms YugabyteDB is a Consistent/Partition Tolerant (CP) database.

YugabyteDB has two layers, a storage engine known as DocDB and the Yugabyte Query Layer.

Architecture Block Diagram for YugabyteDB — YugabyteDB Architecture

DocDB

The storage engine consists of a customized RocksDB combined with sharding and load balancing algorithms for the data. In addition, the Raft consensus algorithm controls the replication of data between the nodes. There is also a distributed transaction manager and Multiversion concurrency control (MVCC) to support distributed transactions.

The engine also exploits a Hybrid Logical Clock^[9] that combines coarsely-synchronized physical clocks with Lamport clocks to track causal relationships.

The DocDB layer is not directly accessible by users.

YugabyteDB Query Layer

Yugabyte has a pluggable query layer that abstracts the query layer from the storage layer below. There are currently two APIs that can access the database:

YCQL is a Cassandra-like API based around v3.10 and re-written in C++. YCQL is accessed via standard Cassandra drivers using the native protocol port of 9042. In addition to the 'vanilla' Cassandra components, YCQL is augmented with the following features:

Transactional consistency - unlike Cassandra, Yugabyte YCQL is transactional.
JSON data types supported natively
Tables can have secondary indexes

YSQL is a PostgreSQL code-compatible API based around v11.2. YSQL is accessed via standard PostgreSQL drivers using native protocols. It exploits the native PostgreSQL code for the query layer and replaces the storage engine with calls to the pluggable query layer. This re-use means that Yugabyte supports many features, including:

Triggers & Stored Procedures
PostgreSQL extensions that operate in the query layer
Native JSONB support

Currently, data written to either API is not accessible via the other API

The security model for accessing the system is inherited from the API, so access controls for YSQL look like PostgreSQL, and YCQL looks like Cassandra access controls.
