Description

This PR associates the Lucene major version with each uploaded segment file metadata entry that is maintained in remote store. As part of the Lucene version compatibility check, this major version information stored in the metadata will be used to skip downloading the segment files unnecessarily if they were written by an incompatible Lucene version.

  1. For the segment files that house the segment data (.cfe, .cfs, etc.), we track the Lucene major version as captured in the respective SegmentInfo instance.

  2. For the segment_N files that house the information on segments, we track the Lucene major version used for the commit as captured in the respective SegmentInfos instance.

  3. For the _<segmentNumber>_<monotonicallyIncrementingCountOfUpdate>_Lucene<major><minor>_<bugfix>.dvm, _<segmentNumber>_<monotonicallyIncrementingCountOfUpdate>_Lucene<major><minor>_<bugfix>.dvd, and _<segmentNumber>_<monotonicallyIncrementingCountOfUpdate>.fnm files, we track the Lucene major version available in the respective .dvm/.dvd file's name.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-8088-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 611ecc2ad50c7e1833e7fe8ef2a6cabeb6028c57
# Push it to GitHub
git push --set-upstream origin backport/backport-8088-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-8088-to-2.x.
