we have had numerous reports on some config
values not having default values, causing
features misbehaving and not having default
values set properly.
This PR tries to address all these concerns
once and for all.
Each new sub-system that gets added
- must check for invalid keys
- must have default values set
- must not "return err" when being saved into
a global state() instead collate as part of
other subsystem errors allow other sub-systems
to independently initialize.
- 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
