Hi Arjun

Your first option sound good
But if we make it as db column unique then we will not be able to store duplicate email

We have two cases in our project first is incognito mood where duplicate email can be accepted and other non congnito mood where duplicate email can not be accepted
If I do so it will break our existing feature

I have given my answer as per your initial question.

Hi!!!! I am working on a project and it has registration page for user where I am using email address for validation purpose if email exists we are throwing error message like email already exists.
But today I am seeing it’s not behaving as expected

When I open registration page in two different browsers one is chrome another one is mozilla at same time then I am able create user with same email without getting any error.

In database only I’d is different for both user but email is same which should no be.

Can any suggest me how to prevent this issue???

This project is written in java
It’s a springboot microservices project

One more thought is there in my mind to use redis

But I don’t have any idea on redis

How its works

Hi akhil

Same thought first came into my mind by later I realised that this will create performance issue

Don’t you think ??

its simple key and value thats it like a hash map

Yes @rocky

I don’t know about rate rate but it’s hardly take few nano second

yup then use it, it will work fine
