Subject [jira] [Commented] (GEODE-292) Optimize speed of backup/ restore cache snapshots
Date Fri, 28 Aug 2015 16:30:47 GMT


Kirk Lund commented on GEODE-292:

Wes, on the far right under People are Assignee and Reporter. Directly under "Unassigned"
is "Assign to me" (a link in blue). You can click that to assign to yourself, or if you click
on "Unnassigned" it let's you enter a name. I'll assign it to you.

>             Project: Geode
>          Issue Type: Improvement
>          Components: persistence
>    Affects Versions: 1.0.0-incubating
>            Reporter: Wes Williams
>              Labels: backups, performance
>             Fix For: 1.0.0-incubating
>   Original Estimate: 120h
>  Remaining Estimate: 120h
> Backup/ restore using snapshots takes a very, very long time when:
> 1) There are a lot of PDXTypes, and
> 2) There are a lot of regions.
> Specifically, it takes 35 minutes to restore only 50MB of unstructured JSON from snapshots.
In contrast, it takes only 3 minutes to reload all the data from scratch.
> CacheSnapshot loops all regions and saves all cache PDXTypes in every region.gfd. On
restore, it reloads all cache PDXTypes again for every region where they only need to be loaded
> This JIRA issue will create an option to save PDXTypes only once and reload them once
and store only data in the region snapshots. Existing functionality will remain for those
who want it.
