Re: [geomesa-dev] Query result is unstable on geomesa_2.11-2.1.0 against

[Emilio Lahr-Vivaz <elahrvivaz@xxxxxxxx>]

Hello,

There currently shouldn't be any functional difference between the two filters. We originally thought that HBase filters had to be implemented in java (JSimpleFeatureFilter). We later re-implemented it in scala (CqlTransformFilter) to standardize our codebase, and we added some serialization caching to improve performance.

I'll try again to reproduce the issue.

Thanks,

Emilio

Hi GeoMesa Devs,

  Thanks you very much for your advice. By adding  try/catches around the filter evaluation code as well as a copying of geotools filter, we recompiled the coprocessor jar and put it into the program. It was pity that although no exception was found in the region server log, the query result was still unstable and various. I want to the what is the improvement of CqlTransformFilter against JSimpleFeatureFilter and the key difference between them.

Thanks again
