How do you go about understanding code of a database system like MySQL/Postgres?
I always wonder since the code of database system is vast, how does once go about understanding it and start contributing to it.
Once you can add small changes like print statements it becomes yours to control and slowly understand.
Step two is multiplying the amount of hours needed by a factor of 10 or 100. Don’t underestimate the time needed to start understanding. Biggest mistake many mortals make.
