[Writable Warm] Composite Directory implementation and integrating it with FileCache #12782

rayshrey · 2024-03-20T08:16:07Z

Description

Implements and design Composite Directory (and integrates it with FileCache) which can fall back to the on-demand fetch when requested data is not present locally.

Opening this PR to get initial review comments on the design and implementation of Composite Directory in this issue - #12781, hence haven't added any tests apart from one IT test for testing the basic functionality. Will include tests in the following revisions to this PR.

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:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.x
# Create a new branch
git switch --create backport/backport-12782-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 b8c78196438897132f6819460ebb7d4222b39297
# Push it to GitHub
git push --set-upstream origin backport/backport-12782-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-12782-to-2.x.
