Constantly high memory usage of managed timescale instances

Hi guys,

we are using a managed timescale instance which has constantly high memory usage (~80% of 16GB).
Is that something which is expected because of some caching functionality I’m not aware of?

Any advice in that regard is appreciated!
(e.g. How to find out the root cause for the high resource consumption. Is 16GB not enough in general to run timescale?)

Thanks in advance!
