I'm the author of Imposm 3 (https://github.com/omniscale/imposm3/) and I'm
working on a new command that will automatically download and import diff files
from planet.openstreetmap.org as they appear.
Normally, it should only make two requests per minute when using minutely
replication. One for the state and one for the osc.gz file. But after the
initial import it will download the diff files as fast as Imposm can import
them till it catches up with the live updates.
A fast server should be able to process 100 diffs per second and more,
especially when only a smaller extract is imported. My question: Is this OK, or
should I add a throttle for this?
As Yves said the best plan would be to use daily diffs until you get to
the current day, then hourlies and only switch to minutelies when you
get to the last hour.
