Use a script or a cron job to repeatedly copy master data to Redis.

This pre-caches the data for fast retrieval.

Read the master data from MongoDB on application startup and store a copy of the data in Redis.

To serve master data from Redis, preload the data from MongoDB. And you can do that even when you rely primarily on MongoDB as a persistent data store. Examples of master data lookup include fetching data for user interface (UI) elements (such as drop-down dialogs, select values, multi-language labels), fetching constants, user access control, theme, and other product configuration.

You can address access and manipulation operations so that data consistency is preserved and data access happens quickly.įrom a developer’s point of view, master data lookup refers to the process by which master data is accessed in business transactions, in application setup, and any other way that software retrieves the information. That presents an opportunity to speed things up.

Country lists, genres, and movie languages usually stay the same. Master data generally changes infrequently. That’s a working definition of master data, especially when it also represents the organization’s core data that is considered essential for its operations. One ongoing developer challenge is to (swiftly) create, read, update, and (possibly) delete data that lives long, changes infrequently, and is regularly referenced by other data, directly or indirectly.

You can follow along with the details using the code on GitHub. Cache and database: Redis stack (using Docker).This tutorial uses a GitHub sample demo that was built using the following tools: Each movie card has edit and delete icons, which are displayed when a mouse hovers over the card. The search section has a text search bar and a toggle link between text search and basic (that is, form-based) search. The floating plus icon displays a pop-up when the user selects it, permitting the user to enter new movie details. The movie application dashboard contains a search section at the top and a list of movie cards in the middle.

Building a movie applicationįor the purposes of this post, our demonstration application showcases a movie application that uses basic create, read, update, and delete (CRUD) operations.

Our intent is to help you understand when and how to use this particular pattern in your own software development. We explain the pattern in detail and accompany it with an overview, typical use cases, and a code example. In this post, we share one popular design pattern that developers use with Redis to improve application performance with MEAN and MERN stack applications: the master data-lookup pattern. But it doesn’t mean the software generated runs as fast as it can-or as fast as it needs to. In contrast, the MERN stack is made up of MongoDB, the Express and ReactJS frameworks, and Node.js.īoth stacks work well, which accounts for their popularity. It is a pure JavaScript stack that helps developers create every part of a website or application. The MEAN stack is made up of the MongoDB database, the Express and Angular.js frameworks, and Node.js. Two development stacks that have become popular ways to build Node.js applications are the MEAN stack and the MERN stack. A design pattern has four parts: a name, a problem description (a particular set of conditions to which the pattern applies), a solution (the best general strategy for resolving the problem), and a set of consequences. So what are design patterns? They are recommended practices to solve recurring design problems in software systems. Over time, the development community has learned common techniques that work as reliable design patterns to solve well-understood problems, including application performance. If you don’t design and build software with attention to performance, your applications can encounter significant bottlenecks when they go into production.
