If you want to query the api you can use

area[~"."~"."];out count;

<meta osm_base="2016-09-04T20:30:02Z" areas="2016-09-04T20:15:02Z"/>
  <count total="104367" nodes="0" ways="0" relations="0"/>

I did an initial db load with 49728-ireland-and-northern-ireland.osm.pbf
(including meta, lz4 compression for bin and map), and created areas
(unmodified areas.osm3s script). Total size for areas was 107 MB. Total
size for the db 1.5 GB.

My total size was about 1.5GB when I did initial import.

I started on sequenceNumber=50048 timestamp=2016-09-01T12:30:02Z so using 49728-ireland-and-northern-ireland.osm.pbf from 2016-08-29 should be close.

At some stage after replication is turned on area_blocks.bin increased from ~100MB to ~5GB and later again to 11GB.

It has now increased again to 15GB!

  area[~"."~"."];out count;

produces

  <count total="104219" nodes="0" ways="0" relations="0"/>

Can you please post the exact steps to replicate, including:
* which file to use for an initial load,

Use 49728-ireland-and-northern-ireland.osm.pbf

 

* which replication_id to use for updates

The weekly files are named sequencenumber-ireland-and-northern-ireland.osm.pbf so use 49728

 

* when to run the area creation and how often

I followed the standard install docs so after replication was enabled I just ran

nohup $EXEC_DIR/bin/dispatcher --areas --db-dir=$DB_DIR > dispatcher_areas.out &
nohup $EXEC_DIR/bin/rules_loop.sh $DB_DIR > rules_loop.out &

 

* any other important changes we should be aware of.

Only change I have is to apply_osc_to_db.sh to sleep for 300 instead of 60 as diffs are created every 15 minutes.

 

Thanks
