----------------------------------
Summary: Investigate reducing NodeStore access for permissions defined in
immutable mounts (was: Investigate caching of permissions defined in immutable
mounts)
> Investigate reducing NodeStore access for permissions defined in immutable
> mounts
> ---------------------------------------------------------------------------------
>
> Key: OAK-9518
> URL: https://issues.apache.org/jira/browse/OAK-9518
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, security
> Reporter: Angela Schreiber
> Assignee: Angela Schreiber
> Priority: Major
>
> when running oak with additional immutable mounts, the permission provider
> will come with a composite {{MountPermissionStore}} that loads entries from
> the different mount points.
> while for the mutable default mount reading the latest permission data from
> the {{NodeStore}} is required whenever the cache gets invalidated, this is
> probably not needed for immutable mounts.
> the goal of the this improvement is to investigate if and under which
> circumstances repeated reads for the immutable mounts can/should be prevented
> and measure the impact on overall performance. this includes taking
> potentially huge amounts of permission entries into account and define
> boundaries in case such an improvement was beneficial for mounts with
> relatively few permissions.
