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.Includes:
Managed caching
Ephemeral (in-memory) data buckets Memory-optimized global secondary indexesELASTIC 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 applicationrequirements.
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:
Multi-Dimensional ScalingPERSISTENCE
Couchbase Server’s architecture guards against most forms of failure, and protects against data loss. Buckets can be configured for replication to create data redundancy and to allow for the failure of copies – as long as the data is available somewhere, it’s not lost. Data is also written to the disk, so in the case of a power outage or software crash, data can be retrieved from the disk during recovery. Depending on durability and performance requirements, users can configure the right durability options to meet their applicationneeds.
Includes:
Durability configurationsTRANSACTIONS
Couchbase Server provides high availability for reading and writing of data through a variety of features. Couchbase provides high availability using intra-cluster replication and index replication, and disaster recovery using cross datacenter replication (XDCR). INTRA-CLUSTER REPLICATION Intra-cluster replication involves replicas that are placed on another node in the same cluster. In the event of failure of a single node, this ensures that data is still available on other nodes that can provide full read and write ability to the applications. CROSS DATACENTER REPLICATION Using the cross datacenter replication (XDCR) capability, you can set up replication of data between clusters. XDCR helps protect against datacenter failures and also helps maintain data locality in globally distributed mission-critical applications.INDEX REPLICATION
Index replication support has been added to improve high availability and manageability of indexes. Users can specify the number of replicas to create, and the system will manage the placement of the index replicas on different index nodes, server groups, and availabilityzones.
Includes:

Couchbase Server provides high availability for reading and writing of data through a variety of features. Couchbase provides high availability using intra-cluster replication and index replication, and disaster recovery using cross datacenter replication (XDCR).

Couchbase Eventing is a highly available, performant and scalable service which enables user-defined business logic to be triggered in real-time on the server when application interactions create changes in data. Eventing makes it easy to develop, deploy, debug and maintain data-driven functions from a centralized platform. Natively integrated with the Couchbase Data Platform, it requires no third party solutions to license or new dataops skills to manage.Learn more:

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 datamodel.
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 availableJDBC/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 ofJSON.

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 andinfrastructure.
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 searchesExpand
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.Includes:
FTS in Couchbase Server FTS in Couchbase Mobile Full-Text Search (FTS) product pageINDEXING
An index is a data structure that provides a quick and efficient means to query and access all your data without scanning every document. Applications can query Couchbase Server in one of the following ways: * Using key-value access – Applications directly access data through the data service with document keys for fastest access * Using N1QL – Applications use SQL-like syntax with global secondary indexes or MapReduce views to speed up queries * Using Couchbase View API directly – Applications directly query the MapReduce view indexes or spatial views for purpose-builtprecomputed indexes
Includes:
Indexing overview
KEY VALUE
Customer experience depends on app performance and behavior, which in turn depends largely on database performance and throughput. At the heart of the Couchbase Data Platform is a distributed key-value (KV) data store. It’s an extremely simple, lightning fast, schemaless data management system that stores a unique ID (key) and a piece of arbitrary information (value). The key is hashed by the Couchbase client library, automatically sharded, and directly sent to the appropriate data service node in the Couchbase cluster. The KV store is accessed using simple create, read, update, delete (CRUD) APIs, and thus provides a simpler interface when accessing documents using their IDs (primary keys). Due to their simplicity, KV operations execute with extremely low latency, often sub-millisecond. Applications can access data stored in the Couchbase Data Platform using a variety of interfaces, including the KV API, MapReduce views, N1QL queries, Full Text Search, and the Analytics Service. For simple CRUD operations using the primary key, the KV API is the fastest and most efficient way of accessing the data.Includes:
Key-value data accessMOBILE
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 existingecosystem.
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.

FULL-STACK SECURITY
Although security is fairly standard in the relational database world, in the NoSQL world it varies significantly from product to product. With Couchbase, your data is secure everywhere – on the wire, on the device, in the cloud, and in the datacenter. The Couchbase Data Platform provides built-in and configurable full-stack security for authentication, authorization, encryption over the wire, and auditing. Via our technology partners, we also provide encryption, data masking, and field-level security.Includes:
Couchbase Server security Couchbase Mobile authentication Couchbase security best practices Security in Couchbase Mobile deployments CONTAINER AND CLOUD DEPLOYMENTS A cloud-first strategy is key to constant innovation and the ability to respond to fast-changing business needs. However, a successful cloud-first strategy must weigh the options of public, private, hybrid, and multi-cloud deployments, while trying to avoid vendor lock-in and unforeseen operational issues. The Couchbase Data Platform is cloud-native and architected to work on any cloud. Differentiated functionality like auto-sharding, shared-nothing, memory-first architecture, Multi-Dimensional Scaling, cross datacenter replication (XDCR), zone- and region-aware replication, and a cloud-based Sync Gateway make Couchbase uniquely suited for cloud deployments. Couchbase provides easily deployed pre-built modules on AWS, Google Cloud Platform, and Microsoft Azure marketplaces. Couchbase also supports a variety of container and virtualization technologies, including partnerships with Joyent, Docker, and Red Hat OpenShift, to enable operational excellence across any kind of public, private, hybrid, or multi-cloud deployment.Includes:
