Impossible d'interroger avec deux index d'attributs dans le type d'entité geomesa

Question

J'interroge une entité geomesa qui comprend l'index join sur deux attributs (r et di). La requête r=<int-value> exécute et renvoie des données pour la valeur r spécifiée, le cas échéant. Cependant, la requête di=<int-value> ne trouve aucun enregistrement correspondant bien que des enregistrements existent pour le même!

Voici mon schéma caractéristique:

r:Long:cardinality=high:index=join,*g:Point:srid=4326,di:Integer:index=join,al:Float,s:Float,b:Float,an:Float,he:Float,ve:Float,t:Float,m:Boolean,i:Boolean,ts:Long;geomesa.table.sharing='true',geomesa.indices='attr:4:3,records:2:3,z2:3:3',geomesa.table.sharing.prefix='\\u0001'

Je ne suis pas en mesure de trouver la cause racine. Est-ce que je ne peux pas avoir plus d'un index d'attribut dans un schéma?

Je résolu ce problème en ajoutant des transformateurs manquants dans le plugin ombre Maven pour choisir diverses implémentation d'exécution comme ci-dessous
