Re: [geomesa-users] Creating Attribute Indexes
|
Yeah, it took me a while to find it myself. This question has come up a
few times recently - we'll reorganize the docs a bit to make it easier
to find.
Thanks,

Thanks. Don't know how I missed that example.
Wasn't expecting to find that information under Data Management.

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,

This is probably a simple question and may be stupid.
We are programmatically creating SimpleFeatureTypes from our data
structures
at run time. Right now we are using SimpleFeatureTypeBuilder.
In the code we specify the geometry and date fields for that indexing.
We want to create an index on an attribute when we create that
feature type.
I see where I can use the CLI add-attribute-index command to create
such an
index. But in the usage text it states that it runs a mapreduce job
to create the
index which implies that it can only be created after all data is
ingested.
Is there a way to programmatically create an index when the
FeatureType is created?
