Stay ahead of today’s intensive data processing requirements
Change is a constant. It continuously challenges architects and developers to design and develop revolutionary applications that are more flexible and versatile. While applications may start small, user bases inevitably explode and their requirements change, new regulations come into effect and evolve, and breaches can surprise at any time. Our NoSQL document database and key-value store was purposefully designed to minimize these impacts. Couchbase is architected for change.
Couchbase architectural advantages
Develop with agility
Time to market is critical, separating the first mover from everyone else. Developing an application today without knowing all of its needs at the outset requires a database that provides flexibility in schema and access patterns. As a document database, Couchbase empowers developers to build responsive, flexible applications at scale.
- Flexible schema for continuous delivery
- Fully featured SQL for JSON database
- No hassle scale out
Flexible schema for continuous delivery
- Flexible JSON data model enables on-the-fly schema change for continuous delivery
Fully featured SQL for JSON database
- SQL extended to JSON for query and analytics, including support for JOINs
- Storage, retrieval, structured querying, full-text search, real-time analytics and triggers, in the cloud or on mobile and edge devices
No hassle scale out
- Application behavior unchanged on 1-node development laptop to multi-node production deployment
- No manual sharding, or re-sharding
Perform at any scale
Raw speed isn’t enough. The experience of the first user must be as seamless for the millionth and beyond. Gone are the days of weekend maintenance windows. You must be available all the time, anywhere around the globe. As a distributed scale-out database, Couchbase guarantees consistent performance all day, every day, for all users.
- Memory and network centric
- Always-on, edge-to-cloud
- Consistent performance at any scale
Memory and network centric
- Memory-first architecture with integrated document cache
- Network-centric architecture with a high-performance replication backbone allows new workloads to be easily added while maintaining performance at scale
Always-on, edge-to-cloud
- Architected as a scale-out distributed database across physical, virtualized, container, and public cloud environments
Consistent performance at any scale
- Intelligent, direct application-to-node data access without additional routing and proxying
- Independent data and index partitioning to optimize mixed and varied workloads
- Multi-Dimensional Scaling enables workloads to be added quickly and scaled independently with no impact on the existing performance
Manage with ease
Distributed databases are hard. Couchbase makes it easy. A single platform integrates storage, access, transport, and enterprise-grade security on premises and across multiple clouds and mobile devices. Administration and maintenance is abstracted from the application behavior: scale out, in, or up; replicate around the globe; upgrade versions; and recover from failures with zero downtime or application changes.
- Global deployment with low write latency
- Consistent performance when adding microservices
- Full stack security
Global deployment with low write latency
- Active-active cross datacenter replication (XDCR) with flexible topologies and low latency
- Hybrid-cloud deployment and management with Docker containers and Kubernetes/OpenShift Operator
Consistent performance when adding microservices
- Auto-sharding, replication, and failover for easy scale out and high availability
- Autonomously maintain application availability 24x365 across upgrades, node failures, network failures, or even cloud provider failures
- All functionality available across physical, virtualized, public cloud, container, and Couchbase Managed Service environments
Full stack security
- End-to-end encryption over the wire and at rest
- Role-based authentication, with support for LDAP, PAM, and X.509
- Data and administrative auditing

Memory First
Customers expect and demand fast, responsive applications. Many enterprises will add an in-memory caching product in front of their relational and NoSQL database to increase performance and throughput, and to ensure responsiveness. However, this adds operational and management complexity as well as additional cost.
Built on a memory-first architecture, Couchbase ensures that all operations occur in-memory and supports special memory-optimized data management options, including 100% memory resident indexes and data buckets. This optimizes data-access performance and throughput while also simplifying operational management and reducing costs. By achieving memory-speed data transfer between nodes in the cluster, Couchbase avoids traditional database disk I/O bottlenecks.
Expand
The Couchbase Data Platform leverages its memory-first architecture to transfer data between nodes in the cluster at the speed of memory, thus avoiding traditional database disk I/O bottlenecks.
Elastic Scalability
As part of the core database engine, Couchbase provides an elastic Multi-Dimensional Scaling (MDS) architecture that supports both scale-up and scale-out approaches.
MDS allows you to separate the different data processing workloads as distinct, independently scalable services. You can independently configure and scale (up or out) the data, index, query, Full Text Search, and Analytics Services based on your data management processing requirements and application workloads. This gives you both the scalability to deliver responsive customer applications and the flexibility to adapt to new and changing workloads and application requirements.
Expand
MDS is particularly well-suited for the cloud where compute, storage, and memory resources are typically allocated and expensed separately. MDS allows you to independently configure and scale your compute, storage, and memory resources for each service. This results in a more efficient allocation and use of resources, ultimately reducing your overall cost of operations in the cloud.
Includes:
Query
Build and evolve web, mobile, and IoT apps faster using Couchbase’s own query language, N1QL (“nickel”). N1QL combines the power and familiarity of SQL with the flexibility and agility of the JSON data model.
N1QL is a declarative query language that extends SQL for JSON data. You can query data via native framework and language integrations, a fluent and easy-to-use API, several Couchbase utilities, or available JDBC/ODBC drivers.
With N1QL you can query JSON documents without any limitations: sort, filter, transform, group, and combine data with a single query. You can combine data from multiple documents with a JOIN. And you’re not limited to the “single table” and “table per query” data models often found in other NoSQL products.
Expand
In the Couchbase Mobile 2.0 release, N1QL has also been added to Couchbase Lite. This allows mobile application developers to leverage their existing SQL programming skills along with the flexibility of JSON.
Analytics
Powerful parallel query processing over JSON data allows you to:
- Efficiently execute complex, long-running SQL-like queries that contain complex joins and set, aggregation, and grouping operations
- Address the challenges of supporting responsive, scalable apps and ad hoc analytics on the same dataset
Couchbase Analytics powerfully combines a common JSON data model with:
- A SQL-like query language extended for JSON
- Effective analytical workload isolation
- Up-to-date data freshness via a fast memory-to-memory transfer protocol in a single platform
This allows app developers and DevOps to build intelligent applications and dashboards that surface insights to customers and business users in real time without the overhead and latency of performing separate extract, transform, load (ETL) operations.
Expand

Full-Text Search
Built-in Full-Text Search (FTS) makes it simple for developers to add intelligence to apps. Full-text indexes are automatically managed within the Couchbase cluster, avoiding the delay, overhead, and complexity of managing a separate full-text search product and infrastructure.
FTS enables you to create, manage, and query full-text indexes on JSON documents stored in a Couchbase bucket. It provides powerful capabilities for natural language queries, including:
- Stemming, which provides a language-aware manner of searching (e.g., users can type "beauties" and find results for "beauty")
- Scoring, which provides relevance ranking for results
- Fast multipurpose indexes where a single index can support a wide range of possible text searches
Expand
In the Couchbase Mobile 2.0 release, Full Text Search has also been added to Couchbase Lite. This allows mobile application developers to incorporate device-local FTS queries and intelligence into their mobile applications.
Mobile
Couchbase gives you a full-stack data platform for your mobile and IoT apps, including built-in real-time data synchronization, enterprise-level security, and data integration with your existing ecosystem.
Your mobile and IoT apps leverage the full power of the Couchbase Data Platform by using Couchbase Server, Couchbase Sync Gateway, and Couchbase Lite to enable secure online and offline data access, as well as automatic data synchronization from device to the backend.
Data integration APIs let you integrate with your existing systems of record, data warehouses, and other legacy systems via Sync Gateway or Couchbase Server.
Expand
Whether you have hundreds, thousands, or millions of devices, Couchbase Server and Sync Gateway are independently scalable in real time, enabling you to keep up with changing demands.
