At least from my observations mapproxy doesn't seem to hold a global db lock while waiting for the pics in the seeding process to materialise ... if it did, that would be a _major_ bug.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 23 Mar 2021 at 13:20, Travis Kirstine <<a href="mailto:traviskirstine@gmail.com">traviskirstine@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">My experience is that all the sqlite based caches work great once the data is cached, however caching can be a bit slow. I'm not sure how or if it is possible but try to ensure MapProxy is exporting / converting multiple tiles per transaction or you could be in for a very long wait.<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 22 Mar 2021 at 17:58, Immanuel Hayden <<a href="mailto:immanuel.hayden@gmail.com" target="_blank">immanuel.hayden@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Oooh that looks like just what I'm looking for.

So far I've found geopackage to work rather nicely and also seemingly uses considerably less disk space (about half in my trials). However this leads to two questions:</div><div class="gmail_default"><br></div><div class="gmail_default">1. Did anyone ever do a performance comparison between the different local caches? I am concerned with running into performance problems halfway through converting the data. This also includes resource consumption (i.e. does for example loading a geopackage cache stress memory more than a file cache?)</div><div class="gmail_default">2. Is there some way to convert between cache types? Re-rendering takes a _long_ time due to the complexity of our maps, so while this was a good option for my test projects, it isn't for the bulk of the tile cache. If there is an option, how would I actually set that up? Maybe adding the existing cache as a WMS soure or something?</div><div class="gmail_default"><br></div><div class="gmail_default">Thanks for your inputs :)</div></div></div></div>
