Hello,
Has anyone done articles or advocacy for Postgres in embedded applications?
I am fooling around with Home Assistant on a Raspberry Pi. This is a
Python 3 app that is normally backed by SQLite. But it has issues
because often times more than one process wants to write to the
database, and SQLite doesn't do that well. I found a handy guide on
replacing SQLite with PG in this application:
https://community.home-assistant.io/t/howto-postgresql-on-raspberry-pi-all-in-one-installer/5527/21
Two things I noticed right off the bat. The UI of HomeAssistant is
MUCH faster using PG than it is using SQLite. We're talking 5 seconds
for a page refresh vs half a second. Second, Postgres is tiny! The
whole stack- OS, Postgres, HASS server- takes up a whopping 67 MB of
RAM.
It'll be interesting to see how these stats change as I leave the
thing running for months on end.
Cheers!
