Look like I need to rewatch 3 or 4 times to consume the information. Honestly, a little bit overwhelming for me who has been learning web development and related technologies for (only) over a year. And also, Thank You, Gio. I've reached this far and I'm going to rewatch the entire playlist again.
Hi Gio. Thanks a lot for this. I was able to make my own 1k and 10k samples. It all worked like you said. I'm curious to see the refactor since we had to comment out the addTransaction on the set category and on the set user functions. These optimization techniques are very insightful Gio. You teach things that people hide. Thanks you so much
Hi, could you cover multiple file/image upload with some server-side resizing and cropping etc? Basically what lacks is not the uploading, it's the optimization so that they upload fast. Without any special tweak, multi-image upload with ajax is really slow. Would love if that's covered. As always, great great series.
Answer is "it depends" :D. You can solve that using different types of locks, optimistic/pessimistic locks, again depending on the data you are trying to access. In most cases its a row-level locking so it locks that specific row so unless you have many concurrent transactions trying to do something with the same row there should be no issues. And if that becomes an issue there is solution for it too, but it again depends on the situation.
