YDB and CAP/PACELC theorem #154

Open grolegor opened 1 year ago

grolegor commented 1 year ago

How to categorise YDB using CAP/PACELC theorem? If it's even possible due to the fact that these theorems aren't ideal (please stop calling databases CP or AP) But categorising distributed system using these theorems still has some basic value though. How to do it for YDB? Maybe it depends on settings of YDB cluster. Could you elaborate on this please. It might be useful for developers who are thinking about migration to YDB.
