> Allow individual deltas to trigger bucket size recalculation
> ------------------------------------------------------------
>
> Key: GEODE-8894
> URL: https://issues.apache.org/jira/browse/GEODE-8894
> Project: Geode
> Issue Type: New Feature
> Components: core, serialization
> Affects Versions: 1.14.0
> Reporter: Raymond Ingles
> Priority: Major
> Labels: pull-request-available
>
> The Redis subsystem uses Deltas heavily, but by default deltas do not trigger
> an update to the size of their buckets. This leads to incorrect memory usage
> accounting over the long term, especially with the use of Redis commands like
> "APPEND".
> It is possible to set the system property "DELTAS_RECALCULATE_SIZE", but this
> is a global value that would affect the processing of all deltas, including
> non-Redis operations.
> Instead, we will add a new default method to the Delta interface, that can be
> overridden by individual Delta implementations (such as Redis). This will
> trigger the same behavior as DELTAS_RECALCULATE_SIZE, but on a per-delta
> basis. Thus, other Geode operations will not force bucket size recalculations
> unless the global property is set, but Redis statistics will be correct.
> Other types of delta operations may find this useful in the future.
