Wei-Chiu Chuang updated HDDS-15313:
-----------------------------------
Release Note:
ozone.om.snapshot.diff.max.allowed.keys.changed.per.job: default raised from
10,000,000 to 1,000,000,000 (1 billion). Medium snapshot diff jobs were hitting
the old limit too quickly.
ozone.om.snapshot.diff.max.page.size: default raised from 1,000 to 5,000, so
the server-side max page size is higher than the CLI default and can be tuned
independently.
> Increase snapshot diff defaults

> Key: HDDS-15313
> URL: https://issues.apache.org/jira/browse/HDDS-15313
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Saketa Chalamchala
> Assignee: Saketa Chalamchala
> Priority: Major
> Labels: pull-request-available
>
> Most snapshot diffs at large scale clients are observed to run into the
> `ozone.om.snapshot.diff.max.allowed.keys.changed.per.job=10M` limit very
> soon.
> As this limit only verifies the estimated number of keys to iterate and not
> the actual diff need to increase it and issue a warning to the client to
> either continue or cancel instead of rejecting the snapshot diff.
> Another threshold, we need to increase is the
> `ozone.om.snapshot.diff.max.page.size=1000(default)`. Both the default page
> size and max page size are set to 0. It makes sense to have the max limit be
> higher than the default so that the default page size can be increased
> gradually without having to increase max page size too often.
