> TarMK cold standby: ensure client integrity
> --------------------------------------------
>
> Key: OAK-2113
> URL: https://issues.apache.org/jira/browse/OAK-2113
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-next
> Reporter: Manfred Baedke
> Priority: Minor
>
> TarMK cold standby needs measures to ensure the integrity of each segment on
> the slave and that all segments that are reachable on the master from a given
> segment are available on the slave.
> To ensure the integrity of a given segment on the slave, we can just use the
> checksum stored in the segment, so there is no need to change the
> communication protocol for this.
> To ensure that all segments that are reachable from a given segment are the
> same on the master and on the slave, we need a new request to calculate a
> suitable checksum on the master and send it back to the slave.
> If missing or broken segments are detected, the slave will pull them from the
> master again.
> Both measures combined should be scheduled to run regularly.
