Good question, Here is the detailed answer of your question on How to ensure Redis cache has most updated data 1. Cache Invalidation on Update Whenever data is updated in the database, immediately invalidate or update the corresponding cache entry. Implementation Steps: Update the Database: Perform the update operation on the database. Invalidate Cache: Remove or update the relevant key in Redis. Example in Node.js: const redisClient = require('./redisClient'); // assuming you've set up your Redis client const db = require('./databaseClient'); // your database client async function updateData(id, newData) { // Update the database await db.update(id, newData); // Invalidate the cache await redisClient.del(`data:${id}`); } async function getData(id) { // Check the cache first let cachedData = await redisClient.get(`data:${id}`); if (cachedData) { return JSON.parse(cachedData); } // If not in cache, fetch from the database let data = await db.get(id); // Store in cache for future requests await redisClient.set(`data:${id}`, JSON.stringify(data)); return data; } 2. Write-Through Cache When updating data, write the new data to both the database and the cache simultaneously. Example in Node.js: async function updateData(id, newData) { // Update the database await db.update(id, newData); // Update the cache await redisClient.set(`data:${id}`, JSON.stringify(newData)); } 3. Cache with Expiry (TTL) Set a time-to-live (TTL) for cache entries. This ensures that even if cache invalidation is missed, the stale data will eventually expire and be refreshed from the database. Example in Node.js: async function getData(id) { let cachedData = await redisClient.get(`data:${id}`); if (cachedData) { return JSON.parse(cachedData); } let data = await db.get(id); // Store data with an expiry time (e.g., 60 seconds) await redisClient.setex(`data:${id}`, 60, JSON.stringify(data)); return data; } 4. Event-Driven Cache Invalidation Use events to trigger cache invalidation. Whenever the database updates, it emits an event that listeners (like the cache layer) can act upon. Example with Event Emitters: const EventEmitter = require('events'); const cacheInvalidationEmitter = new EventEmitter(); cacheInvalidationEmitter.on('dataUpdated', async (id) => { await redisClient.del(`data:${id}`); }); async function updateData(id, newData) { await db.update(id, newData); cacheInvalidationEmitter.emit('dataUpdated', id); } By using one or a combination of these strategies, you can ensure that your Redis cache reflects the latest data from your database. Hope this answer will resolve your query, if not? feel free to ask here again and I will make a proper practical video on your boubt and will ensure you will get a proper answer

@@sandeepdev0 saw you using grafana and k6 in this. So dedicated video will be great. You make great content

I will try to make a dedicated video on this topic to answer your query. It's highly dependent on the kind of web app you're building. For example, if your web app requires image manipulation and you want a built-in CDN, then Cloudinary is a great option. It's much simpler to use. However, if you have strong AWS knowledge and don't need extensive image manipulation, then AWS S3 + CloudFront is definitely the way to go. It's generally cheaper than Cloudinary, but it may be a bit more complicated to implement at first. For reference, I developed a SaaS product for a foreign client whose web app currently manages approximately 89,000 images with an average size of 3MB per image. I used AWS S3 + CloudFront for their product, and their monthly bill is around $115. Please note that pricing may vary depending on the region.

sure✅, in Next video

Micro service architecture, low level system design (coding patterns), scalable system, Full stack Ai SaaS web apps creation etc. all these stuff is coming soon... where you will will how to write quality code, how to test everything, and much more stuff

@@sandeepdev0 Bhaiya waiting for this

#chaiaurcode #backend

aap sabhi ka pyaar and suport hai bhai💖

Yes the process will be same, just way of writing code in nextjs backend is little bit different, but its almost exactly same

It will be deployed normally as we deploy nextjs apps, You can deploy on vercel and any other cloud platform

You're welcome! 💓

Noted ✅ , Will make a video on this soon
