title: Is there a good way to display map tiles dynamic and real time?
body: <p><strong>Ⅰ using python-mapnik(linux)+postgis</strong></p>
  
  <p>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</p>
  
  <p><strong>Ⅱ using python(flask)+postgis(MVT)+mapbox-gl</strong></p>
  
  <p>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</p>
  
  <p>Now I don't know how to complete my research about displaying big vector tiles fast and realtime!!</p>
  
  <p>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.</p>
  
  <p>some information about vector tiles I've found,maybe is useful to somebody like me：</p>
