How Does Caching Work in Django?

Hazelcast Community
by Hazelcast Community | Dec 06, 2021

Most web applications often persist data from one request to the next. Web applications are dynamic, making calculations and database queries to serve requests. This overhead can be expensive, especially when we need the same data repeatedly.  Django-based applications are no exception to this challenge. Ideally, we’d like a place to persist data between requests […]

How Does Caching Work in ASP.NET Core?

Hazelcast Community
by Hazelcast Community | Nov 29, 2021

Generating content served from an ASP.NET application can be slow and expensive — particularly when there’s heavy use of database calls. Relational databases are historically challenging to scale. Implementing caching means that the application doesn’t have to fetch and process the same data again and again. It’s one of the most effective ways to improve […]

Querying Your IMDG: Why and How?

Nicolas Frankel
by Nicolas Frankel | May 12, 2021

Where would you draw the line between a data store and a cache? Persistence? Hazelcast allows you to write your in-memory data on disk. Derived data vs. source of truth? If the cost of creating the data is cheap, why would you persist them? Let’s agree that there’s no clear-cut defining property but a blurry […]

by Sergii Bishyr | Apr 26, 2021

The JDBC API was the first way to connect and execute queries on databases in Java and is still widely used today.

From Embedded to Client-Server

Nicolas Frankel
by Nicolas Frankel | Apr 15, 2021

Java developers are particularly spoiled when using Hazelcast. Because Hazelcast is developed in Java, it’s available as a JAR, and we can integrate it as a library in our application. Just add it to the application’s classpath, start a node, and we’re good to go. However, I believe that once you start relying on Hazelcast […]

Contract-First Development Using RestAssured and OpenAPI

Bence Eros
by Bence Eros | Mar 22, 2021

Contract-first development is a methodology where we first create a design document (or interface definition) that formally describes the REST API we are going to implement, before writing any actual prototype. This methodology is useful for clearly communicating the structure and capabilities of the upcoming API before we implement it. Given a formal description of […]
