How to import YAML structure in etcd

Question

We have below YAML structure which consists of multiple key / values pair . these are basically dictionary kind of structure used in kubernetes . Instead of keeping these configuration items in YAML file , we thought to use the key/value store database to maintain these config values.

after analysis , we laned into etcd . however, from the docs , it appears that , single key / value can be easily stored in etcd , but what about dictionary/array kind of structures where single key might have multiple values .

is etcd is right database for our requirement ? please suggest
