@elahrvivaz Hi Emilio , I have a question, why does build-and-test always fail in my PR? I have not modified the content of the test code.

thanks for working through things!

oh, the build is failing due to one of the metadata impls not implementing the new method you added:

/home/runner/work/geomesa/geomesa/geomesa-kafka/geomesa-kafka-confluent/src/main/scala/org/locationtech/geomesa/kafka/confluent/ConfluentMetadata.scala:24: class ConfluentMetadata needs to be abstract, since method resetCache in trait GeoMesaMetadata of type ()Unit is not defined
Error:  class ConfluentMetadata(val schemaRegistry: SchemaRegistryClient) extends GeoMesaMetadata[String] with LazyLogging {

(the error about needing to be abstract is wrong, you just need to add an impl for the resetCache() method)

Sorry, my project only includes geomesa-hbase and related content. I have modified to rewrite the build with a complete project, and now it can be successful.
