Add ordering of files in compound files (#12241) 
Today there is no specific ordering of how files are written to a compound file.
The current order is determined by iterating over the set of file names in
SegmentInfo, which is undefined. This commit changes to an order based
on file size. Colocating data from files that are smaller (typically metadata
files like terms index, field info etc...) but accessed often can help when
parts of these files are held in cache.

Build Status

Online Documentation

This README file only contains basic setup instructions. For more comprehensive documentation, visit:

Building

Basic steps:

  1. Install OpenJDK 17 or 18.
  2. Clone Lucene's git repository (or download the source distribution).
  3. Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.

See Contributing Guide for details.
