CockroachDB is a commercial distributed SQLdatabase management system developed by Cockroach Labs.[1][2]CockroachDB is a distributed SQL database built on top of a transactional and consistent key-value store that can withstand datacenter failures. It scales horizontally.[3]
While at Google, all three had used Google-owned DBMS’s Bigtable and its successor, Spanner.[2] After leaving Google, they wanted to design and build something similar.[6] Spencer Kimball wrote the first iteration of the design in January 2014, and began the open-source project on GitHub in February 2014, allowing outside access and contributions.[7]
Development on GitHub attracted substantial contributions, which earned the project the Open Source Rookie of the Year award by Black Duck Software.[8]
The co-founders supported the project with conferences, networking, meet-ups, and fund-raising financial rounds.
In June 2019, Cockroach Labs announced that CockroachDB would change its license from the freesoftware licenseApache License 2.0 to its source-available license, known as the Business Source License (BSL), which forbids “offer[ing] a commercial version of CockroachDB as a service without buying a license,” while remaining free for community use.[9][10]
Featuresedit
CockroachDB stores copies of data in multiple locations to deliver quick access.[6][11]
CockroachDB is designed to run in the cloud and has a high fault tolerance. According to popular news outlets, it is described as “almost impossible” to take down. [13][14][11]
CockroachDB has a consistency model that is designed to match as closely as possible to the capabilities of Google Spanner, but without a dependence on specialized hardware for time synchronization. "No stale reads" is the simplest way to describe this consistency model which has deliberately made the trade-off of having non-linearizable transaction histories.[15] Transactions containing overlapping keys are guaranteed to have external consistency. And so, in practice, systems relying on CockroachDB are very unlikely to reproduce consistency issues because nodes with high variations in clock skew can be removed from clusters, applications can rely on external consistency provided by overlapping keys and writing to the same range, and writes propagate changes to followers' timestamp caches.[16]
