[jira] [Created] (SOLR-10286) Declare a field as "large", don't
keep value in the document cache
David Smiley created SOLR-10286:
-----------------------------------
Summary: Declare a field as "large", don't keep value in the document cache
Key: SOLR-10286
URL: https://issues.apache.org/jira/browse/SOLR-10286
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: David Smiley
Assignee: David Smiley
(part of umbrella issue SOLR-10117)
This adds a field to be declared as "large" in the schema. In the {{SolrIndexSearcher.doc(...)}} handling, these fields are lazily fetched from Lucene. Unlike {{LazyDocument.LazyField}}, it's not cached after first-use unless the value is "small" < 512KB by default. "large" can only be used when its stored="true" and multiValued="false" and the field is otherwise compatible (basically not a numeric field) -- you'll get a helpful exception if it's unsupported. BinaryField is not yet supported at this time; it could be in the future.
