Distributed SQL-based querying
The business world is undergoing massive change as enterprises are shifting toward a digital economy. At the core of every digital economy business are its web, mobile, and Internet of Things (IoT) applications. They are the primary means through which companies interact with customers today and run more and more of their business. The experiences that companies deliver through these applications largely determine customer satisfaction and retention.
Today’s enterprise applications share one or more of the following characteristics. They need to:
● Support large numbers of concurrent users (tens of thousands, or perhaps even millions, of users)
● Deliver highly responsive experiences to a globally distributed base of users
● Be always available, no downtime
● Handle semistructured and unstructured data
● Rapidly adapt to changing requirements with frequent updates and new features
Building and running these applications has created a new set of technology requirements. The enterprise data platform must be more agile and scalable, and its approach to real-time data management must accommodate new levels of speed and data variability.

Couchbase Server is a popular database system used to power the growing digital economy. Its core architecture is designed to simplify building modern applications with a flexible data model, a powerful SQL-based query language, and a secure core database platform that provides high availability, scalability, and performance.
Couchbase Server can be deployed in multiple ways:
● Document database: Access, index, and query documents while taking advantage of integrated caching for high-performance data access.
● Key-value store: Meet high-performance requirements for read and write data access while maintaining data durability and availability.
● Distributed cache: Provide scalable, low-latency access to large in-memory data sets, optionally through the memcache API and clients.
Couchbase enables applications to run with consistent high performance while supporting very high rates of throughput. Couchbase can also scale easily and efficiently: from a few nodes to many nodes and from one data center to multiple data centers, with push-button simplicity. A comprehensive, web-based console simplifies management and monitoring by performing complex tasks and providing more than 200 metrics covering everything from cluster health to individual node performance. Figure 1 shows the real-time flow of data with Couchbase.
Real-Time Data Flow with Couchbase
Typical use cases for Couchbase include the following:
● User profile management
● Operational dashboards
● 360-degree customer view
● Real-time data processing
● High-availability caching
● Metadata management
The Cisco UCS Integrated Infrastructure for Big Data and Analytics for Couchbase includes eight or more C240 M5 (or C220 M5) servers, each with 2nd Generation Intel Xeon Gold 5218R Processor (2 x 20 cores and 2.1GHz), 384 GB of RAM, dual 40-Gbps network connectivity, and 8 (or 16) solid-state disks (SSDs). These servers are connected to Cisco UCS 6332 Fabric Interconnects (Figure 2).
Several tests were performed to demonstrate the performance of Couchbase on Cisco UCS Integrated Infrastructure at a large scale. The tests focused on the most critical components for real-time analytics: ingestion and retrieval. Couchbase Server delivered high performance for both as the system scaled out from four nodes to eight nodes. These tests validate the linear scalability and high performance of Couchbase on Cisco UCS Integrated Infrastructure.
The test configuration consisted of four to eight Cisco UCS C240 M4 Rack Servers, each with two 2nd Generation Intel Xeon Gold 5218R Processor (2 x 20 cores and 2.1GHz), 192 GB of RAM, eight 1.6-TB SATA SSDs with Couchbase Server 4.6.1 Enterprise Edition software, and the Red Hat Enterprise Linux (RHEL) 7.2 operating system.
Initial set of tests were run on a 4-node cluster that was later scaled out to an 8-node cluster. Multiple tests were performed using 50:50 and 95:5 read-write ratios:
● With 100% data present in memory
● With 50% data present in memory
The Couchbase bucket for storing data was created using the default setting for data compaction and a replica setting of 1, which means that for each data record, Couchbase Server automatically created a second copy to support high availability.
All tests were performed using cbc-pillowfight, a load-generation tool created by Couchbase. (The source code for this tool is publicly available at GitHub.)
