Reactive Couchbase

Explore nonblocking and responsive database interactions through reactive programming with Spring Data Couchbase.

We'll cover the following...

Spring Data Couchbase provides support for reactive programming with the Couchbase NoSQL database. It allows using nonblocking, asynchronous operations and reactive data streams to handle concurrent requests efficiently, resulting in highly scalable and responsive applications that can handle large workloads and achieve high throughput.

Quick Setup

First, we add the spring-boot-starter-data-couchbase-reactive Spring Boot starter data dependency to the build.gradle file to enable reactive programming support for Spring Data Couchbase.

plugins {
    id 'java'
    id 'org.springframework.boot' version '2.7.5'
    id 'io.spring.dependency-management' version '1.1.0'
}
group = 'com.smartdiscover'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
    mavenCentral()
}
dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-couchbase'
    implementation 'org.springframework.boot:spring-boot-starter-data-couchbase-reactive'
    implementation 'org.projectlombok:lombok:1.18.26'
    annotationProcessor 'org.projectlombok:lombok'
}

Reactive Couchbase repository

The ReactiveCouchbaseRepository interface is provided by Spring Data Couchbase for reactive programming, extending the ReactiveSortingRepository interface.

package org.springframework.data.couchbase.repository;
public interface ReactiveCouchbaseRepository<T, ID> extends ReactiveSortingRepository<T, ID> {
	ReactiveCouchbaseOperations getOperations();
	CouchbaseEntityInformation<T, String> getEntityInformation();
}
