Ⅰ using python-mapnik(linux)+postgis
I've tried using mapnik to show big data(aboult more than 600,0000 polygon features with much points in postgis),I display it real time from python service without cache. but i meet the problem: 1.At the beginning,load table from database lost much time 2.when I zoom to 12level,map tile will loading slowly
Ⅱ using python(flask)+postgis(MVT)+mapbox-gl
1.display 100,0000 features(simple polygon) so fast,but display big data(aboult more than 600,0000 polygon features with much points in postgis),i find selet query need much time. it's slowly than mapnik
Now I don't know how to complete my research about displaying big vector tiles fast and realtime!!
Is there a persion like me who are interested in quickly displaying data??Any help or suggestion would be appreciated! At last ,forgive my poor English descrption.
some information about vector tiles I've found,maybe is useful to somebody like me:
