Overpass API developpement

[Donal Diamond <>]

I'm using overpass api v0.7.53 using lz4 for for both bin and map compression.

I'm running an Ireland country extract but I've noticed my diskusage has jumped from 1->5->11GB al due to large increases in size in area_blocks.bin.

Is area_blocks.bin compressed or what coudl account for a 10x increase in diskspace when consuming regional diffs?

>/overpass/db$ du -sh *.bin

11G     area_blocks.bin

175M    areas.bin
1.3G    area_tags_global.bin
1.4G    area_tags_local.bin
192K    node_keys.bin
133M    nodes.bin
102M    nodes_meta.bin
14M     node_tags_global.bin
11M     node_tags_local.bin
64K     relation_keys.bin
64K     relation_roles.bin
11M     relations.bin

119M    ways.bin
17M     ways_meta.bin
38M     way_tags_global.bin
17M     way_tags_local.bin


>/overpass/db$ du -sh *.map
