gianm opened a new issue #6653: Poor throughput when flattenSpecs refer to missing maps
URL: https://github.com/apache/incubator-druid/issues/6653
 
 
   I observed a cluster earlier today that had poorer than expected throughput for an Avro ingest that had a lot of flattenSpecs. After some profiling I believe it is related to this json-path issue: https://github.com/json-path/JsonPath/issues/396
   
   Maybe we could work around it by claiming (in GenericAvroJsonProvider) that nulls are maps, and then having the mappy methods like getPropertyKeys, getMapValue, etc have do-nothing behavior on them.
