Re: [geomesa-users] Inconsistent temporal filtering, sometimes inclusive

[Hunter Provyn <fhp@xxxxxxxx>]

Beau,

Thank you for bringing this to our attention.
I have reproduced this issue and created the following ticket:

https://geomesa.atlassian.net/browse/GEOMESA-215

We are working on a fix so that querying is always exclusive of temporal filter bounds. This is consistent with how opengis Filter.evaluate behaves for temporal filters.

I'll notify you when it is fixed.

thanks,
Hunter

Hi,

 

I am using a mid-June version of GeoMesa.  Perhaps this issue has been fixed since mid-June, but if it hasn’t been I thought I should report it.

 

I have noticed that GeoMesa seems to inconsistently handle the temporal portion of a filter.  In particular, I notice that sometimes the temporal portion of a filter seems to be inclusive and sometimes it seems to be exclusive.  

 

When I perform a query, the temporal component seems to be inclusive, but when I try to remove features, the temporal component seems to be exclusive.

 

For example, when I use the following filter (filter result reported by ECQL.toCQL(filter)) for querying, data with the geomesa_time attribute set to 2014-01-01T05:20:00+00:00 is returned; however, when I use the same filter to try to remove features, data with the geomesa_time attribute set to 2014-01-01T05:20:00+00:00 is not removed.

    ((geomesa_time BEFORE 2014-02-05T05:30:00+00:00 AND geomesa_time AFTER 2014-01-01T05:20:00+00:00) AND BBOX(geomesa_geometry, -100.008,39.969,-99.999,39.978))

 

I would prefer that each temporal bound be inclusive (as I find it to be when querying), but most importantly I would like the behavior to be consistent.  I should note, that I also want the behavior to work consistently for modifying features.

 

My query code is analogous to the following:

    FeatureSource<SimpleFeatureType, SimpleFeature> featureSource = dataStore.getFeatureSource(featureName);

    FeatureCollection<SimpleFeatureType, SimpleFeature> featureCollection = featureSource.getFeatures(new Query(featureName, filter, properties));

 

My removing of features code is analogous to the following:

    featureStore.removeFeatures(filter);

 

 

Please let me know if I can be of any further help with troubleshooting. 

 

Thanks,

 

Beau
