Spring Data Reactive Repositories with Couchbase 1. Overview In this tutorial, we’ll learn how to configure and implement database operations in a reactive way on Couchbase using Spring Data Repositories. We’ll cover the basic usages of ReactiveCrudRepository and ReactiveSortingRepository. Additionally, we’ll configure our test application with AbstractReactiveCouchbaseConfiguration. 2. Maven Dependencies Firstly, let’s add… Continue Reading spring-data-reactive-couchbase

Querying Couchbase with MapReduce Views 1. Overview In this tutorial, we will introduce some simple MapReduce views and demonstrate how to query them using the Couchbase Java SDK. 2. Maven Dependency To work with Couchbase in a Maven project, import the Couchbase SDK into your pom.xml: <dependency> <groupId>com.couchbase.client</groupId> <artifactId>java-client</artifactId> <version>2.4.0</version>… Continue Reading couchbase-query-mapreduce-view

Asynchronous Batch Operations in Couchbase 1. Introduction In this follow-up to our tutorial on using Couchbase in a Spring application, we explore the asynchronous nature of the Couchbase SDK and how it may be used to perform persistence operations in batches, thus allowing our application to achieve optimal use of… Continue Reading async-batch-operations-in-couchbase

Introduction to Couchbase SDK for Java 1. Introduction In this introduction to the Couchbase SDK for Java, we demonstrate how to interact with a Couchbase document database, covering basic concepts such as creating a Couchbase environment, connecting to a cluster, opening data buckets, using the basic persistence operations, and working… Continue Reading java-couchbase-sdk

Using Couchbase in a Spring Application 1. Introduction In this follow-up to our introduction to Couchbase, we create a set of Spring services that can be used together to create a basic persistence layer for a Spring application without the use of Spring Data. 2. Cluster Service In order to… Continue Reading couchbase-sdk-spring

Intro to Spring Data Couchbase 1. Introduction In this tutorial on Spring Data, we’ll discuss how to set up a persistence layer for Couchbase documents using both the Spring Data repository and template abstractions, as well as the steps required to prepare Couchbase to support these abstractions using views and/or… Continue Reading spring-data-couchbase

Multiple Buckets and Spatial View Queries in Spring Data Couchbase 1. Introduction In this third tutorial on Spring Data Couchbase, we demonstrate the configuration required to support a Couchbase data model that spans multiple buckets, and we introduce the use of Spatial views for querying multi-dimensional data. 2. Data Model… Continue Reading spring-data-couchbase-buckets-and-spatial-view-queries

Querying Couchbase with N1QL 1. Overview In this article, we’ll be looking at querying a Couchbase Server with N1QL. In a simplified way, this is SQL for NoSQL databases – with the goal of making the transition from SQL/Relational databases to a NoSQL database system easier. There are a couple… Continue Reading n1ql-couchbase

Entity Validation, Optimistic Locking, and Query Consistency in Spring Data Couchbase 1. Introduction After our introduction to Spring Data Couchbase, in this second tutorial we focus on the support for entity validation (JSR-303), optimistic locking, and different levels of query consistency for a Couchbase document database. 2. Entity Validation Spring… Continue Reading entity-validation-locking-and-query-consistency-in-spring-data-couchbase
