[OSM-talk] OSM Postgres table sizes (was: Failed to download 9.5 GB planet)

2010-06-24 Thread Juan Lucas Domínguez Rubio
Hello, thanks.

Solved. I think the problem was that I was downloading the file to a remote 
disk (R: mapped to \\lanserver\data)

Another question: after exporting the whole planet (recently) to Postgres, what 
is the size of the largest table created (which I presume will take up 80% of 
the whole DB)? You can get the table size with:

SELECT pg_size_pretty(pg_total_relation_size('big_table'));

Regards,
Juan Lucas

 Try a different mirror, or try it via ftp. (if that's possible)


Can anyone confirm if there is a problem with the heanet mirror?

Juan: you could try FTP or rsync too.

or
rsync://ftp.heanet.ie/mirrors/openstreetmap.org/planet-100618.osm.bz2

I can't speak for the whole planet.osm file (so this might be useless),
but I have (roughly) an extract of the United States.  The largest table,
planet_osm_ways, is 50 GB.  The next-largest table, planet_osm_nodes, is
21 GB.  After that is planet_osm_line at 8 GB.

based on my planet and minutely mapnik:

8 GB polygon
21 GB line
2 GB point
43 GB nodes
3 GB roads
50 GB ways
4 GB rels

overall disk use ~ 130 GB and growing about 2.5 GB/week at the moment.

Hello, thanks.
That's much more than what I expected. With a small example, I obtained a 1:3 
ratio between the .osm format and the table size, so I estimated ~50 GB for the 
whole DB.

Juan Lucas

I'm not sure I understand your question.

You can import a bounding box or extract and have smaller tables.

You can import without --slim, if you have the hardware for it, and
lose some large tables.  But then you lose the ability to update
unless you do a re-import.

Other alternatives?

Over time, the overhead increases, not just the amount of data.

I didn't mean without the slim option.

That's my question, how to eliminate overhead in the database without
re-importing.
