What is Couchbase?

Couchbase Server is an open source, distributed NoSQL document-oriented database.

Couchbase is one of leading NoSQL database technology solutions and the Couchbase open source project provider. It is a document-oriented distributed database, operating as the mix of two widely used NoSQL technologies: Membase and CouchDB.

The platform keeps up with all customer, employee, and machine interaction, serving as a powerful NoSQL for all kinds of massively interactive enterprises. It is developed on a memory-first structure, which maintains demanding data management options and makes operational management simpler. Another feature is elastic scalability and multi-dimensional scaling architecture, able to adapt to existing and new workloads and software requirements.

Couchbase also implements a query mechanism to recover data in cases of clients' query that is distributed to all servers in the cluster. The platform's persistence feature ensures data loss protection, thanks to the replication of data storing and data redundancy creation. There are intra-cluster, cross-datacenter, and index replication combinations offered.

Couchbase Review

Editors' Review by the Big Data Software Review Team

Couchbase is the company behind Couchbase Server, an avant-garde cloud-native, distributed database capable of combining the power of relational databases like ACID and SQL with the adjustability of JSON.

Couchbase Server is a robust and feature-rich database management solution designed to serve small and midsize enterprises (SMEs) and large companies across multiple industries such as finance, hospitality, energy, information technology (IT), retail, telecommunications and manufacturing. The system allows these organizations to retrieve, organize, store, modify, and aggregate relevant corporate data. Couchbase delivers a multi-model NoSQL database specifically tailored for mission-critical applications, helping provide richer and more personalized customer and employee experiences.

Developed using NoSQL technology, the Couchbase database solution is founded on an open-source architecture geared towards the massively interactive enterprise. Its geo-distributed engagement database aims to deliver manageability and agility for developers, as well as higher performance and efficiency at scale.

Couchbase Server is equipped with a query workbench, which enables developers and DevOps teams to modify queries with syntax coloring, multi-line formatting and auto-completion of N1QL keywords. It also allows them to view different document structures and present query results in easily digestible tree, table and JSON formats. This cloud database system empowers supervisors to check prepared, completed and active queries, including information such as request ID, duration and nodes.

Administrators and supervisors can leverage the built-in role-based access control, encryption, certification and auditing features of Couchbase to secure their data. The platform allows seamless integration with third-party systems like RedHat OpenShift and Kubernetes, which automates the scaling, configuration and recovery of Couchbase data clusters. Other features offered by Couchbase Server include document import, ad hoc analysis, cross-data center replication, JavaScript eventing and full-text search capabilities.

Couchbase Features

The following are some of the key features and capabilities of Couchbase Server that make it unique from all other similar products:

Database query language N1QL

Couchbase features an intuitive NoSQL query language that enables you and your team to handle even the toughest production and adoption challenges out there, such as unpredictable performance, high migration cost and data inconsistencies. N1QL provides app developers a powerful, expressive and comprehensive declarative language for querying, manipulating and transforming relevant data in JSON format. This feature allows for queries that are similar to SQL, but with the flexibility of JSON.

With N1QL as your database querying language, you and your team of developers can quickly adapt to the ever-changing business and industry requirements through a schemaless JSON document store. It allows you to query without any compromise and scale anytime without restrictions, thanks to a high performance NoSQL query engine that comes with a built-in indexer and optimizer, allowing millions of concurrent interactions with sub-millisecond latencies.

Multi-dimensional scaling (MDS)

Multi-dimensional scaling or MDS provides innovative distributed architecture, offering compute, storage and processing workload partitioning in order to tackle the ever-changing needs of end users. It works on the idea that one size never fits all when it comes to the scaling of a business or its operation. MDS gives SMEs and developers the ability to implement Couchbase Services with enough flexibility across all hardware resources. Individual clusters can then be effectively fine-tuned for optimum handling of evolving workload requirements.

On the other hand, additional hardware resources, i.e. disk capacity, memory, CPU, etc., may be added to targeted nodes within the cluster to support and improve the performance of other key operations and services. MDS includes the ability to provision individual services independent from each other, which enables IT teams and developers to scale service performance individually up and down as necessary. This approach offers the best flexibility when it comes to managing the ever-changing business requirements.

ACID transactions for NoSQL apps

Couchbase has the power to support distributed multi-document ACID database transactions at scale, with high performance and availability. With this functionality, you will be able to migrate all your relational database apps to Couchbase and get ACID compliance while benefiting from a robust and reliable SQL support.

In the world of database management, ACID is an acronym that describes the best practices on how to process transactions in a consistent, secure and reliable manner. ACID means atomicity, consistency, isolation and durability.

Eventing service from Couchbase

This robust database management system offers real-time server-side event processing through service referred to as Couchbase Eventing. This is a highly available, high-performing and scalable event processing service that allows user-defined business logic to be automatically triggered on the server in real time when specific application interactions create changes or modifications to the data. Eventing is designed to make it easier for teams to develop, deploy and maintain data-driven business logic through a secure and centralized platform.

The Eventing service is natively integrated with Couchbase. It doesn’t require third-party solutions to license or new DataOps knowledge and skills to successfully manage. With Couchbase Eventing, you should be able to streamline your entire business operation and app services by managing business logic closer to the most relevant data.

JSON analytics

Couchbase lets you optimize your analytics pipeline through its analytics tools, which allow you to effectively measure real-time business operations in order to derive meaningful insights, come up with immediate data-driven decisions and ensure growth. This functionality is crucial for businesses and organizations where architectural complexity is restricting their ability to obtain valuable insights from operational data.

Couchbase’s analytics solutions are designed to shorten the time to acquiring insights, maximize analytics agility and ensure operational simplicity. The solution brings NoETL to NoSQL, effectively allowing businesses and organizations to capture rich and dependable real-time insights from their operational data at scale.

Couchbase Benefits

The following are some of the key benefits of Couchbase Server and how it can help your data administrators and IT teams manage queries for simple to complex databases:

Visually design queries with relative ease

Couchbase is equipped with a well-designed user interface for its Query Workbench feature, which gives you and your team the power to optimize NoSQL queries by visually profiling the agreed execution plan. Indexes have automatic replication and transparent partitioning, allowing the delivery of high performance and availability for all business-critical applications. This is what Couchbase’s database query language is all about.

Delivers unmatched agility and flexibility

Couchbase’s Eventing and analytics solutions deliver great flexibility and agility for data managers and developers. Couchbase Eventing leverages JavaScript programming with an interactive visual debugger to make it easier and more efficient for developers to create, test and manage data-driven business apps that are closer to the data.

Alternatively, the unmatched agility and flexibility that Couchbase’s analytics tools bring to the table are quite impressive. For one, you can analyze operational data in near real-time while minimizing costs by simply removing a separate layer for analytical data. You may also ingest, consolidate and analyze data from different Couchbase data groups and datacenters in a more centralized cluster that’s purely dedicated to the analytics service.

High performant data analytics at any scale

Couchbase offers unparalleled analytics performance at any scale. The platform gives you the ability to run analytical queries at any magnitude, leveraging its massively parallel processing (MPP) engine. The MPP engine is designed to scale linearly with the flexibility to integrate capacity on demand with exceptional performance. This approach can drastically reduce the time to insight (TTI) from your NoSQL data.

In addition, MDS or multi-dimensional scaling allows for analytical queries that are configured on dedicated nodes, which are then optimized independently and isolated from operational workloads.

Easy to use and manage analytics platform

Couchbase Server’s analytics architecture is considerably easy to adopt, manage and maintain. The platform features a user-friendly web-based management console where you can easily add nodes with just a few simple clicks. You and your team are also afforded the ability to simplify key operations with analytical and operational workloads within a single unified platform, while benefiting from optional workload isolation right out of the box.
