I read tilesize doc v2.1. In the doc, it says tilecache support mbtiles and amazon cloud storage.</div>
</div></blockquote><div><br></div><div>You're right. Sorry, my bad. A cache persistent in MBTiles will not scale as well as other options. Theoretically, a sqlite db could be terabyte-sized (<a href="http://www.sqlite.org/features.html" target="_blank">http://www.sqlite.org/features.html</a>) but keep in mind that the access to the tiles would degraded just after a few gigabytes. I don't know if TileCache follows the same strategy as MapProxy regarding tiles with the same RGB (i.e. lake areas) as it reuses tiles permitting huge disk space savings.</div>
