[Tile-serving] Recommended OSM update method?

[Imre Samu]

> "update in batches approximately monthly"

in theory:  you can generate an osm change file from 2 osm monthly planet
files [  https://planet.openstreetmap.org/pbf/  ]

example:
first import      : planet-220307.osm.pbf   ( in the database )
next monthly batch: planet-220404.osm.pbf   ( planned import. )

And using https://docs.osmcode.org/osmium/latest/osmium-derive-changes.html

you can create OSM change files from the two OSM monthly planet files.

osmium derive-changes planet-220307.osm.pbf planet-220404.osm.pbf -o
*planet-diff-220307-220404.osc.bz2*

in theory,  the "planet-diff_220307_220404.osc.bz2" change file is smaller
than the sum of ( daily changes files )

disclaimer:  in theory == not tested in real life.

regards,
  Imre
