> Recon List Keys API: Reuse key prefix if parentID is the same
> -------------------------------------------------------------
>
> Key: HDDS-11668
> URL: https://issues.apache.org/jira/browse/HDDS-11668
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Recon
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
>
> As we iterate keys in the listKeys API there is logic to resolve the FSO path
> to the key which is quite expensive in aggregate over many keys.
> As we iterate the keys in order, it is highly likely there will be
> consecutive keys with the same parent folder and hence prefix.
> Therefore, we should save the prefix prefix and if the current parentID is
> equal to the previous one, simple reuse it, avoiding all the path
> construction work.
