How to build a Spring Boot Apache Geode application?

How to build a Spring Boot Apache Geode application?

For example, you can begin building a Spring Boot, Apache Geode or Pivotal GemFire, ClientCache application with either the spring-geode-starter or spring-gemfire-starter on your application’s classpath: Then, you configure and bootstrap your Spring Boot, Apache Geode ClientCache application with the following main application class:

What is the cacheserver annotation in Spring Boot?

By explicitly declaring the @CacheServerApplication annotation, you are telling Spring Boot that you do not want the default, ClientCache instance, but rather an embedded, peer Cache instance with a CacheServer component, which enables connections from ClientCache apps.

Do you have to run Apache Geode to use pivotal Gemfire?

By default, an Apache Geode or Pivotal GemFire server (i.e. CacheServer) must be running in order to use the ClientCache instance. However, it is perfectly valid to create a ClientCache instance and perform data access operations using LOCAL Regions. This is very useful during development.

How to add caching dependencies in Spring Boot?

If we use Spring Boot, then we can utilize the spring-boot-starter-cache starter package to easily add the caching dependencies: <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-cache </artifactId> <version> 2.4.0 </version> </dependency>

How does Spring Boot auto configure spring data for Apache Geode?

Auto-configures Spring Data for Apache Geode (SDG) Repositories when Spring Data for Apache Geode (SDG) is on the application’s CLASSPATH and Spring Boot detects SDG Repositories in your Spring Boot application to solve persistent use cases.

Which is open source software for Apache Geode?

Spring Boot, Spring Boot for Apache Geode and Spring Boot for Pivotal GemFire is Open Source Software released under the Apache 2.0 license.

What’s the difference between a cache and a geode?

An Apache Geode Region is equivalent to a database table and the cache is equivalent to a database schema. A database schema is a namespace for a collection of tables whereas an Apache Geode cache is a namespace or group of Regions that hold the data. Each data store has its own data structure to organize and manage data.

By explicitly declaring the @CacheServerApplication annotation, you are telling Spring Boot that you do not want the default, ClientCache instance, but rather an embedded, peer Cache instance with a CacheServer component, which enables connections from ClientCache apps.

Is the Apache Geode server the same as the pivotal server?

An Apache Geode/Pivotal GemFire “server” is not necessarily a “CacheServer” capable of serving cache clients. It is merely a peer member in the GemFire/Geode cluster (a.k.a. distributed system) that stores and manages data.

Can you enable embedded locator in Gemfire / Geode?

You can also enable 2 other GemFire/Geode services, an embedded Locator, which allows clients or even other peers to “locate” servers in a cluster, as well as an embedded Manager, which allows the GemFire/Geode application process to be managed and monitored using Gfsh, GemFire/Geode’s shell tool:

By default, an Apache Geode or Pivotal GemFire server (i.e. CacheServer) must be running in order to use the ClientCache instance. However, it is perfectly valid to create a ClientCache instance and perform data access operations using LOCAL Regions. This is very useful during development.
