The yin and yang of programming is adding a layer of indirection to solve a problem but slow everything down, and then adding a layer of caching to speed it back up while adding at least one bug.
This is how we still all have jobs.
My session speaking on Opensource industry conference China will introduce @ShardingSphere@apache_age and Apache brpc. Hope more people know these great projects and have more choices for their #OpenSource journey! (To confess, I am biased for my hat of their PMC or mentor🙃)
