YugabyteDB is a high-performance transactional 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][3] during a period of significant growth in workloads such as Facebook Messenger and Facebook's Operational Data Store.[4]

The founders came together in February 2016 to build YugabyteDB,[5] 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.[6]

YugabyteDB was initially available in two editions: community and enterprise. In July 2019, Yugabyte open sourced previously commercial features and launched YugabyteDB as 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.[7]

Yugabyte launched Yugabyte Cloud,[8] now renamed YugabyteDB Managed, a fully managed database-as-a-service offering of YugabyteDB, in September 2021.[9]

Funding

Six years after the company's inception, Yugabyte closed a $188 Million Series C funding round to become a Unicorn start-up with a valuation of $1.3Bn[10]

Architecture

YugabyteDB is a distributed SQL database that aims to be strongly transactionally consistent across failure zones (i.e. ACID compliance].[22][23] Jepsen testing, the de facto industry standard for verifying correctness, has never fully passed, mainly due to race conditions during schema changes.[24] In CAP Theorem terms YugabyteDB is a Consistent/Partition Tolerant (CP) database.[25][26][27]

YugabyteDB has two layers,[28] a storage engine known as DocDB and the Yugabyte Query Layer.[29]

DocDB

The storage engine consists of a customized RocksDB[29][30] combined with sharding and load balancing algorithms for the data. In addition, the Raft consensus algorithm controls the replication of data between the nodes.[29][30] There is also a Distributed transaction manager[29][30] and Multiversion concurrency control (MVCC)[29][30] to support distributed transactions.[30]

The engine also exploits a Hybrid Logical Clock[31][29] that combines coarsely-synchronized physical clocks with Lamport clocks to track causal relationships.[32]

The DocDB layer is not directly accessible by users.[29]

YugabyteDB Query Layer

Yugabyte has a pluggable query layer that abstracts the query layer from the storage layer below.[33] There are currently two APIs that can access the database:[30]

YSQL[34] is a PostgreSQL code-compatible API[35][36] based around v11.2. YSQL is accessed via standard PostgreSQL drivers using native protocols.[37] It exploits the native PostgreSQL code for the query layer[38] 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[36]
  • PostgreSQL extensions that operate in the query layer[36]
  • Native JSONB support[36]

YCQL[39] is a Cassandra-like API based around v3.10 and re-written in C++. YCQL is accessed via standard Cassandra drivers[40] 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.[41]
  • JSON data types supported natively[42]
  • Tables can have secondary indexes[43]

Currently, data written to either API is not accessible via the other API, however YSQL can access YCQL using the PostgreSQL foreign data wrapper feature.[44]

The security model for accessing the system is inherited from the API, so access controls for YSQL look like PostgreSQL,[45] and YCQL looks like Cassandra access controls.[46]

Cluster-to-cluster replication

In addition to its core functionality of distributing a single database, YugabyteDB has the ability to replicate between database instances.[47][48] The replication can be one-way or bi-directional and is asynchronous. One-way replication is used either to create a read-only copy for workload off-loading or in a read-write mode to create an active-passive standby. Bi-directional replication is generally used in read-write configurations and is used for active-active configurations, geo-distributed applications, etc.

Migration tooling

Yugabyte also provides YugabyteDB Voyager, tooling to facilitate the migration of Oracle and other similar databases to YugabyteDB.[49][50] This tool supports the migration of schemas, procedural code and data from the source platform to YugabyteDB.
