I was looking for dev/production specs for QuestDB the other day and didn't see them in the docs. Being that it's in Java, which can be quite memory-hungry, what's the minimum and recommended RAM/CPU required to run it?
Our startup sequence is sub-optimal. We query JDK to index timezone database and JDK generates a tonne of garbage in the process. The whole feat requires roughly 500MB RAM. Once out of startup sequence all this is collected and we can operate in 128MB heap.
The data itself is memory mapped. Columns are kept as primitives so that they take as much memory as their unit size times rows.
Thanks for the explanation, makes sense! Sounds like I could get away with 1GB RAM for development and probably want a bit more of a buffer to be safe in production.
