Hey everyone! I recently developed a web system where every time a user applied a filter, it would trigger a new request to query the database and reload the data each time. This got me thinking—wouldn't it be more efficient to load the data once and then apply filters using JavaScript on the front end, rather than constantly hitting the database?
I'm curious to know about the best practices when it comes to using data structures and algorithms for filtering or searching on the client side versus the backend (which is C# in my case). When is it more efficient to handle filtering on the front-end instead of sending repeated requests to the server? Any insights or examples would be greatly appreciated!

You're right about doing a cost-benefit analysis. Pulling fresh data from the database is slow but ensures you're working with the most up-to-date information. If you're storing data client-side and modifying it, you might end up with stale data, especially if users keep the tab open for a long time. A common strategy is to combine both methods: query the backend and set up some layers of caching to enhance performance while keeping data relevant.
It depends on your data size and access needs. If the data is manageable, it’s often quicker to filter on the front end. But if you're dealing with massive datasets, it’s typically more efficient to handle filters server-side with a caching solution in place. Just make sure your fresh data doesn’t come at the expense of user experience due to lag!
Well, it really depends on the size of your data. If you're dealing with, say, 1,000,000 records, loading all that into the browser just for filtering can chew up a lot of memory and processing power. If you only have a small dataset—like a few hundred records—then client-side filtering might work better. Remember, not all users are on the latest devices; some might be on older phones where performance will really suffer if you load too much data at once. Every millisecond counts, especially if you're running an e-commerce site!
Great point! Also, if your data changes often, querying the database might be better to keep it fresh instead of relying on potentially outdated data stored client-side.
In general, a smaller dataset is more suitable for client-side filtering. If you know users have common filters that can be cached or even embedded on the page, that can be a good trade-off to improve UX, rather than always querying the server. But if you're looking at thousands of records, that could be a whole different ballgame—it might not even be feasible to do it all on the client side!
Absolutely, and don’t forget about bandwidth costs. Sending huge datasets back and forth can lead to performance issues!
True! Plus, consider scenarios where users might have multiple tabs open—loading all that data could lag the browser big time!
