---------------------------
Labels: resilience (was: )
> Tracking the start time of mark in GC for a shared datastore
> ------------------------------------------------------------
>
> Key: OAK-3360
> URL: https://issues.apache.org/jira/browse/OAK-3360
> Project: Jackrabbit Oak
> Issue Type: Sub-task
> Components: blob
> Reporter: Amit Jain
> Assignee: Amit Jain
> Priority: Minor
> Labels: resilience
> Fix For: 1.3.6
>
>
> Currently, for GC in a shared datastore, the last modified timestamp of the
> earliest references file is used to calculate the max age of blobs to be
> deleted. There is a possibility that the process itself could have taken
> quite a long time which opens up a window that recent blobs could also be
> deleted.
> The mark process is quite fast and with the default setting of
> {{blobGcMaxAgeInSecs}} of 24 hours this should not be a problem but if the
> {{blobGcMaxAgeInSec}} is specified to a lower value then it could create that
> window described above.
