@iamareebjamal What is your opinion regarding this?

[iamareebjamal]

@mayank8318 We need to change the implementation of filtering, so if you can take that up, this change will be included there as well

@iamareebjamal I would love to do it. What exactly is required on the issue?

[iamareebjamal]

Correspond to #2066

The filter functionality uses arrays and a lot of unnecessary calculation. We have to reimplement it. Basically, come up with a new solution imagining there isn't one and then change the implementation to that

@iamareebjamal Ok on it :)
