Krishnan Parthasarathi a7577da768 Improve expiration of tiered objects (#18926) ... - Use a shared worker pool for all ILM expiry tasks - Free version cleanup executes in a separate goroutine - Add a free version only if removing the remote object fails - Add ILM expiry metrics to the node namespace - Move tier journal tasks to expiryState - Remove unused on-disk journal for tiered objects pending deletion - Distribute expiry tasks across workers such that the expiry of versions of the same object serialized - Ability to resize worker pool without server restart - Make scaling down of expiryState workers' concurrency safe; Thanks @klauspost - Add error logs when expiryState and transition state are not initialized (yet) * metrics: Add missed tier journal entry tasks * Initialize the ILM worker pool after the object layer		2024-03-01 21:11:03 -08:00
