------------------------------------
Summary: BlockTree's terms index should be loaded into memory
lazily
Key: LUCENE-7834
URL: https://issues.apache.org/jira/browse/LUCENE-7834
Project: Lucene - Core
Issue Type: Improvement
Components: core/codecs
Reporter: David Smiley
Assignee: David Smiley
I propose that BlockTree delay loading the FST prefix terms index into memory
until {{terms(String)}} is first called. This seems like how it should work
since if someone wants to eager load then they can use {{IndexReaderWarmer}}.
By making the FST lazy load, we can be more NRT friendly (if some fields are
rarely used), and also save memory (if some fields are rarely used).
