Greptile Overview

Greptile Summary

Refactored get_opts function across the caching layer to return GetResult instead of Bytes, improving performance for vortex search by avoiding unnecessary data copying and materialization. The change moves the result construction closer to the data source (disk/memory cache), allowing more efficient streaming.

• Disk cache now returns GetResultPayload::File directly with file handle
• Memory cache returns GetResultPayload::Stream wrapping cached bytes
• Storage layer simplified by delegating GetResult construction to cache modules
• Added e_tag generation for better cache validation

Confidence Score: 4/5

• This PR is safe to merge after addressing one potential panic issue in the disk cache range handling.
• The refactoring is well-structured and follows existing patterns. One issue: disk.rs:524 uses .unwrap() on as_range() which could panic on invalid ranges, while memory.rs properly handles this with map_err.
• src/infra/src/cache/file_data/disk.rs - potential panic on line 524
