I want to create a custom iterator and utilize it using GeoTools API.
Currently, I am retrieving data using DataStore and SimpleFeatures objects and trying to find a way to call a custom iterator I have created.
I have pushed a jar file that contains the custom iterator in geomesa-accumulo pod in the classpath. However, I cannot find how to call the custom iterator using the GeoTools library.
The goal is to move processing at the tablet level and I am doing that by creating a custom iterator. However, I cannot find a way (programmatically) to call or invoke the iterators using GeoTools API.
Tech Stack:
Accumulo 2.1.0
GeoMesa tools 4.0.1
Java custom client

I stored the jar file in the accumulo pod, but not sure how to reference or call the iterator. Is this through some configuration or is this done programmatically?
The GeoMesa GeoTools-to-Accumulo-iterator integration is based on custom query hints, which are used to configure Accumulo iterators at scan time. Adding a new iterator would require writing code to configure it. If the iterator would be generally useful to others, please consider contributing it to GeoMesa! (vs writing a custom fork)
However, if your iterator does not depend on query-time configuration, you could configure it to run on every query as a scan-scope iterator through the Accumulo shell.
