Re: [geomesa-users] Data retrieval and Rendering times

[Hunter Provyn <fhp@xxxxxxxx>]

Hi Chris,

We have used GeoMesa to view hundreds of thousands of points, so 26000 features should be no problem.
Are you using master? There have been some recent improvements to the query planner and we are now implementing relational projections, so you should be using master to take advantage of this. Also be sure you are using geoserver 2.5 and geotools 11.0.
I will try to reproduce the issue with your cellular data file and let you know what I find.

Thanks,
Hunter

Hi,

 

My team has been working with geomesa and the accumulo tables for a prototype product.  We have spent  a lot of time learning about accumulo and geomesa.  I was able to use the shapefile ingest class to push the FCC cell towers shapefile (26000+ features) into accumulo and generate a layer in GeoServer.

 

Using the GeoServer preview layers page, we get some pretty information back with WMS requests.  However, at certain zoom levels, the image times out, or the image doesn’t render.  I can click the image at a presumed location and the getfeatureinfo call works and returns the features around my x/y coordinate.  Zooming in or out will generally return the expected image.

 

Are there JVM/memory settings for GeoServer or Accumulo that I can begin looking at tweaking to increase performance?  Is there an expected limitation on the number of features that are returned from a WMS getmap call?
