> Optimize speed of backup/ restore cache snapshots
> -------------------------------------------------
>
> Key: GEODE-292
> URL: https://issues.apache.org/jira/browse/GEODE-292
> Project: Geode
> Issue Type: Improvement
> Components: persistence
> Affects Versions: 1.0.0-incubating
> Reporter: Wes Williams
> Assignee: Wes Williams
> Labels: backups, performance
> 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.
> PROBLEM
> 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 once.
> SOLUTION
> 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.
