cpuShares is the relative weight wrt other apps. This is used when
there is contention for CPU. If we want this, maybe we implement
a UI where we show all the apps and let the user re-order them.
As it stands, it is confusing.
cpuQuota is a more straightforward "hard limit" of the CPU% that you
want the app to consume.
Can be tested with : stress -c 8 -t 20s
Currently, we allocate 50% as RAM and 50% as swap. The manifest is
usually quite conservative on memory values. This means that we set
up a system where the app is applying memory pressure almost immediately.
This then swaps things randomly and increases cpu usage (kswapd shows
up in the profile).
To rethink the whole situation: we should not cap apps with a swap limit at all.
The memory hard limit is what is important. By redefining memoryLimit , we are
doubling every container's memory and it's good that we over allocate this.
* Always show restart button. When using a local VM, you can dynamically
switch flags. So, let the user rebuild. Show error if we cannot.
* The logs button is an "a" tag which is clickable despite ng-disabled
docker is using a extra udp port for every container. when there is
a lot of containers, a lot of random udp ports get used up. this causes
problems when installing apps that require contiguous port ranges
otherwise, when an app is uninstalling, it creates the docker containers
by calling getDynamicEnvironment. This ends up adding addonConfigs for the
docker addon and prevents the app from getting uninstalled.
we used:
psql -Uroot --dbname=postgres --command="ALTER SYSTEM SET shared_preload_libraries = 'vectors.so'"
the above wrote to the auto config file and required a reboot. this resulted in

ADVICE: If you encounter this error for your first use of pgvecto.rs, please read `https://docs.pgvecto.rs/getting-started/installation.html`. You should edit `shared_preload_libraries` in `postgresql.conf` to include `vectors.so`, or simply run the command `psql -U postgres -c 'ALTER SYSTEM SET shared_preload_libraries = "vectors.so"'`.
