Overpass API developpement

Here's 'ls' rather than 'du' output:

could you please post the file sizes of all the area files, i.e.
do a "ls -l" in the db directory and post the result?

Everything else, e.g. the /api/ping call (delivers fresh Irish data), looks fine from outside. In particular, the area process should reuse old data blocks on every cycle, and the best hypothesis I have so far is that it doesn't for an unknown reason. The file sizes of the ".idx.shadow", ".idx" and ".shadow" files should shed some light on that.

Here you go:

/overpass/db$ du -sh area*
17G     area_blocks.bin
4.0K    area_blocks.bin.idx
4.0K    area_blocks.bin.idx.shadow
4.0K    area_blocks.bin.shadow
280M    areas.bin
4.0K    areas.bin.idx
4.0K    areas.bin.idx.shadow
4.0K    areas.bin.shadow
4.0K    areas_shadow.lock
2.0G    area_tags_global.bin
4.0K    area_tags_global.bin.idx
4.0K    area_tags_global.bin.idx.shadow
4.0K    area_tags_global.bin.shadow
2.2G    area_tags_local.bin
4.0K    area_tags_local.bin.idx
4.0K    area_tags_local.bin.idx.shadow
4.0K    area_tags_local.bin.shadow
4.0K    area_version
4.0K    area_version.shadow
