             Summary: Maximum-fields-per-core soft limit
                 Key: SOLR-17192
                 URL: https://issues.apache.org/jira/browse/SOLR-17192
             Project: Solr
          Issue Type: Sub-task
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Schema and Analysis
    Affects Versions: 9.5.0, main (10.0)
            Reporter: Jason Gerlowski
            Assignee: Jason Gerlowski


Solr isn't infinitely scalable when it comes to the number of fields in each 
core/collection.  Most deployments start to experience problems any time a core 
has upwards of a few hundred fields.  Usually this doesn't exhibit itself right 
away. instead waiting until segment-merge or some other time to rear its head.

Sometimes users hit this through intentional schema design.  Often however, it 
happens "accidentally" due to (mis-)use of Solr's "dynamic fields" feature.

We should add a configurable soft-limit, of the type described in SOLR-17191, 
to prevent users from unknowingly getting into this state.
