Hi, There is a recent thread "Replication of Solr Model and feature store" on deploying LTR feature store and model into a master/slave Solr topology.
I'm facing an issue of deploying into SolrCloud (solr 7.5.0), where collections have shards with replicas. This is the process I've been following: 1. Deploy a feature store from a JSON file to each collection. 2. Reload all collections as advised in the documentation: https://lucene.apache.org/solr/guide/7_5/learning-to-rank.html#applying-changes 3. Deploy the related model from a JSON file. 3. Reload all collections again. The problem is that even after reloading the collections, shard replicas continue to not have the model: Error from server at http://server1:8983/solr/collection1_shard1_replica_n1: cannot find model 'model_name' What is the proper way to address this issue and can it be potentially a bug in SolrCloud? Is there any workaround I can try, like saving the feature store and model JSON files into the collection config path and creating the SolrCloud from there?
