Description

  1. Added few more tests for failover and relocation for remote store
  2. Added Remote Translog UT framework . SegmentReplicationWithRemoteIndexShardTests now uses remote translog
  3. Avoid indexing already indexed documents as stale in non primary mode for SegRep based indices .
  4. Added UT for checking no duplicate documents having same sequence number

Testing

Ran RemoteIndexPrimaryRelocationIT 10 times on local to ensure it is not flaky . Running it 100 times more

codecov/patch is failing even after unit tests are added. Bypassing the check.

@sachinpkale sachinpkale merged commit e55dade into opensearch-project:main Aug 3, 2023
9 of 10 checks passed
@sachinpkale sachinpkale added the backport 2.x Backport to 2.x branch label Aug 3, 2023

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-8578-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 e55dadef57809a7fc04dac5ff4d43873beeefadc
# Push it to GitHub
git push --set-upstream origin backport/backport-8578-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-8578-to-2.x.
