CockroachDB
CockroachDB is a source-available distributed SQL database management system developed by Cockroach Labs. The relational functionality is built on top of a distributed, transactional, consistent key-value store that can survive a variety of different underlying infrastructure failures, and is wire-compatible with PostgreSQL which means users can take advantage of a wide range of drivers and tools from the extensive PostgreSQL ecosystem. A CockroachDB cluster consists of a number of nodes that can be spread across failure domains such as data centres or public cloud regions. A cluster can be scaled both horizontally (by adding nodes) and vertically (by increasing the resources allocated to the existing nodes). It can provide high levels of resilience and availability and can be run in a variety of environments such as bare metal, Virtual Machine, VMs, containers and Kubernetes, both in private data centers and in the cloud. CockroachDB gets its name from cockroaches, as they are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distributed SQL
A distributed SQL database is a single relational database which replicates data across multiple servers. Distributed SQL databases are strongly consistent and most support consistency across racks, data centers, and wide area networks including cloud availability zones and cloud geographic zones. Distributed SQL databases typically use the Paxos or Raft algorithms to achieve consensus across multiple nodes. Sometimes distributed SQL databases are referred to as NewSQL but NewSQL is a more inclusive term that includes databases that are not distributed databases. History Google's Spanner popularized the modern distributed SQL database concept. Google described the database and its architecture in a 2012 whitepaper called "Spanner: Google's Globally-Distributed Database." The paper described Spanner as having evolved from a Big Table-like key value store into a temporal multi-version database where data is stored in "schematized semi-relational tables."https://storage.goo ...

Go (programming Language)
Go is a high-level programming language, high-level general purpose programming language that is static typing, statically typed and compiled language, compiled. It is known for the simplicity of its syntax and the efficiency of development that it enables by the inclusion of a large standard library supplying many needs for common projects. It was designed at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson, and publicly announced in November of 2009. It is syntax (programming languages), syntactically similar to C (programming language), C, but also has memory safety, garbage collection (computer science), garbage collection, structural type system, structural typing, and communicating sequential processes, CSP-style concurrency (computer science), concurrency. It is often referred to as Golang to avoid ambiguity and because of its former domain name, golang.org, but its proper name is Go.

Business Source License
The Business Source License (SPDX id BUSL) is a software license which publishes source code but limits the right to use the software to certain classes of users. The BUSL is not an open-source license, but it is source-available license that also mandates an eventual transition to an open-source license. This characteristic has been described as a compromise between traditional proprietary licenses and open source. The originator of the BUSL is MariaDB Corporation AB, where it is used for the MaxScale product, not for the flagship MariaDB. Terms The Business Source License requires the work to be relicensed to a "Change License" at the "Change Date". The "Change License" must be a "license which is compatible with GPL version 2.0 or later". The Change Date must be four years or sooner from the publication date of the work being licensed. The Business Source License by default restricts production use. The license allows copyright owners to specify an "Additional Use Grant ...

Fault Tolerance
Fault tolerance is the ability of a system to maintain proper operation despite failures or faults in one or more of its components. This capability is essential for high-availability, mission-critical, or even life-critical systems. Fault tolerance specifically refers to a system's capability to handle faults without any degradation or downtime. In the event of an error, end-users remain unaware of any issues. Conversely, a system that experiences errors with some interruption in service or graceful degradation of performance is termed 'resilient'. In resilience, the system adapts to the error, maintaining service but acknowledging a certain impact on performance. Typically, fault tolerance describes computer systems, ensuring the overall system remains functional despite hardware or software issues. Non-computing examples include structures that retain their integrity despite damage from fatigue, corrosion or impact. History The first known fault-tolerant computer was ...

Data Store
A data store is a repository for persistently storing and managing collections of data which include not just repositories like databases, but also simpler store types such as simple files, emails, etc. A ''database'' is a collection of data that is managed by a ''database management system'' (DBMS), though the term can sometime more generally refer to any collection of data that is stored and accessed electronically. A file is a series of bytes that is managed by a file system. Thus, any database or file is a series of bytes that, once stored, is called a data store. MATLAB and Cloud Storage systems like VMware, Firefox OS use ''datastore'' as a term for abstracting collections of data inside their respective applications. Types Data store can refer to a broad class of storage systems including: * Paper files * Simple files like a spreadsheet * File systems * Email storage systems (both server and client systems) * Databases **Relational databases, based on the relational m ...

Source-available Software
Source-available software is software released through a source code distribution model that includes arrangements where the source can be viewed, and in some cases modified, but without necessarily meeting the criteria to be called ''open-source''. The licenses associated with the offerings range from allowing code to be viewed for reference to allowing code to be modified and redistributed for both commercial and non-commercial purposes. Distinction from free and open-source software Any software is ''source-available'' in the broad sense as long as its source code is distributed along with it, even if the user has no legal rights to use, share, modify or even compile it. It is possible for a software to be both source-available software and proprietary software (e.g. id Software's '' Doom''). In contrast, the definitions of free software and open-source software are much narrower. Free software and/or open-source software is also always ''source-available software'', but no ...
