Description

Currently tantivy creates empty file even if the schema does not requires them (e.g. no field in the schema is stored for instance). The segment reader also needlessly opens and mmaps these files. jwolfe lost a bit of time when writing a converter from a different search index to tantivy.

Contributor guide

Research direction
Investigate where Tantivy creates empty store, fieldnorm, and position files during indexing, and where the segment reader opens them. Modify the segment writer to skip creating these files when the schema indicates they are not needed, and update the segment reader to handle missing files gracefully.
