I have not introduced that approach on my own, but I took inspiration from other areas of Solr code: such as: org/apache/solr/cloud/api/collections/OverseerCollectionMessageHandler.java:174 org/apache/solr/core/BlobRepository.java:73 org/apache/solr/servlet/HttpSolrCall.java:152 org/apache/solr/util/tracing/GlobalTracer.java:35 So it is already used quite widely across Solr production code. Unless you have stronger concerns we can probably leave it as it is and resolve the conversation here :) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
