How can I reward you for this video? Thank you very much man. Firebase was so complicated to get real time data, but from this your video, a bug I have been trying to fix about 5 days ago is now working 100%.
There are 2 problems here - 1) Each visitor to your page will be querying your database every second with no caching. This will significantly impact the performance of your server. 2) It will take 1 second for your data to populate when the page first loads.
But as of mysql version 8.0 ( I think ) they have removed the cache system completely and I wonder is it because its not up to date anymore? Aren't there other ways to increase query performance for the mysql database?
