Re: [geomesa-users] Creating Attribute Indexes

[Emilio Lahr-Vivaz <elahrvivaz@xxxxxxxx>]

Hi David,

You can set the index hint as user data for the attribute you want 
indexed. Since you're using a SimpleFeatureType builder, you can set the 
hints after building the simple feature type, but before calling 
createSchema. The process is described here (your use case would be the 
second example):

Thanks,

Emilio
