[MULTIPLE ISSUES][STO] Multiple fixes for cloud caching
- user model changes: no
- storage format changes: no
- interface changes: yes
Details:
- ASTERIXDB-3424: Disk cache sweeper can interfere
with rebalance
- ASTERIXDB-3425: Use allocated storage quota to
determine whether or not to persist
non-column pages
- Other fixes:
- Make punchHole() uninterruptible
- Allow plan reevaluation despite the disk is
being pressured or not
- Log the page info when the buffer cache's
page read operation fails
- Fix API tests failures (ASTERIXDB-3423)
- Ignore CloudStorageGCSTest

> Key: ASTERIXDB-3425
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3425
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: STO - Storage
> Affects Versions: 0.9.10
> Reporter: Wail Y. Alkowaileet
> Assignee: Wail Y. Alkowaileet
> Priority: Major
> Fix For: 0.9.10
>
>
> The current policy for persisting a page that was read from the cloud is the
> pressure threshold (determined by CLOUD_STORAGE_SWEEP_THRESHOLD_PERCENTAGE).
> This should not be the case for non-column pages (e.g., BTree interior node
> pages, Page0s, or Metadata pages). Such pages are accessed frequently and
> should be persisted (despite the disk pressure) as long as the storage quota
> (determined by CLOUD_STORAGE_ALLOCATION_PERCENTAGE) permits.
