Relay is actually built by @michael-grunder and @yatsukhnenko and it has the same API as PhpRedis.

Can someone implant client side micro cache solution with specific time period for example 1s 2s 3s changeable by user?

Or additionaly with transparent huge pages using and retry get after specific time period 1s 2s 3s?

But i have here fastest in memory database in the world as library without any stream or datagram sockets overhead .
Everything running inside C function library lockless and scale to millions hits per seconds - even on old hardware like on sandybridge notebooks.

Whitedb domain are reowned by others, here is old homepage backup:

When someone could try whitedb and phpredis amalgamation, this will improve it further and outperform even relay.so

Whitedb will reduce network overhead and bottleneck will be php coroutine itself.

Thanks and

Best Regards

Nginx micro caching working well too, why not phpredis.
