It is <br>intended to some day replace Postgres/PostGIS in the OSM render <br>toolchain. COORDS is developed from scratch (not based on any existing <br>DBMS), and is focused on quickly answering exactly those data queries <br>that are typical for tile servers, while reducing memory consumption and <br>I/O load over Postgres, especially for huge data sets (e.g. planet dumps).<br><br>The first version of COORDS has recently been released as .deb packages <br>for Ubuntu 14.04. These can be found in the PPA <br><a href="https://launchpad.net/~rbuch703/+archive/ubuntu/openstreetmap" target="_blank">https://launchpad.net/~rbuch703/+archive/ubuntu/openstreetmap </a>. <br>Installation and configuration instructions can be found at <br><a href="http://rbuch703.github.io/coords/" target="_blank">http://rbuch703.github.io/coords/ </a>. Manual build instructions are <br>available at the same page, but YMMV as the Mapnik plugin was developed <br>only towards the Mapnik version bundled with TileMill (some 2.3.x <br>developer release).<br><br>This version is yet incomplete (e.g. it handles only OSM ways, no <br>relations or individual nodes), but can already be used as a replacement <br>for Postgres in the OSM render toolchain (demo tile server: <br><a href="http://render.rbuch703.de/" target="_blank">http://render.rbuch703.de </a>; yes, the map style sucks :-) ). Performance <br>comparisons to Postgres are difficult as COORDS is still incomplete, but <br>initial tests look promising: on a 2.4 GHz server with 32GB RAM and <br>HDD-based storage, the import of a planet dump takes only about six <br>hours (Postgres via osm2pgsql takes more than 72h on the same hardware), <br>and rendering the level 3 metatile containing all the world's railway <br>tracks and major roads in the demo map style takes less than a minute.<br><br>At this time, I am mostly looking for people who are willing to test <br>this beta release of COORDS and give feedback of any kind (performance, <br>ease-of-use, suitability for render servers, missing features, ...).<br><br>COORDS is free software, licensed under the AGPL v3 (tools) and LGPL2.1 <br>(Mapnik plugin), respectively.
