COUCHBASE Couchbase Server, originally known as Membase, is an open-source, distributed (shared-nothing architecture) NoSQL document-oriented database that is optimized for interactive applications. These applications must serve many concurrent users by creating, storing, retrieving, aggregating, manipulating and presenting data. In support of these kinds of application needs, Couchbase is designed to provide easy-to-scale key-value or document …
COUCHBASE INTRODUCTION – By Srinivas Maddali – Before you leap some Facts on Couchbase Cluster Design considerations > RAM – depending upon the transactions and data accessed > Number of Nodes – If you are able to deploy more nodes you are distributing the IO as also managing Nodefailures become difficult when the are small …
COUCHBASE HIGH-LEVEL ARCHITECTURE At the highest level, each node in a Couchbase cluster is identical and has two main components: the data manager and the cluster manager. Other important architectural elements are a powerful map reduce engine to incrementally index and query documents, and cross datacenter replication technology to replicate documents across geographical data centers. …
CLUSTER DESIGN CONSIDERATIONS RAM: Memory is a key factor for smooth cluster performance. Couchbase best fits applications that want most of their active dataset in memory. It is very important that all the data you actively use (the working set) lives in memory. CLUSTER DESIGN CONSIDERATIONS memory. When there is not enough memory left, some data …
