David Smiley updated SOLR-18306:
--------------------------------
Component/s: Schema and Analysis
> Dynamic field patterns are applied without caching when retrieving field types
> ------------------------------------------------------------------------------
>
> Key: SOLR-18306
> URL: https://issues.apache.org/jira/browse/SOLR-18306
> Project: Solr
> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 9.10, 10.0
> Reporter: Pierre Salagnac
> Priority: Minor
> Attachments: profiler.png
>
>
> I noticed unexpected CPU usage in {{{}IndexSchema.getDynamicFieldType(){}}}.
> This methods always tries to match a field name by iterating over all dynamic
> field types of the schema. Depending of the number of declared dynamic
> fields, this can be a waste of CPU cycles.
> Since we already have a cache for the fields, we may easily retrieve the type
> for the cache for the fields that are present.
