Karl Wright updated CONNECTORS-13:
----------------------------------
Summary: We should augment file-based synchronization to allow a
process/service-based synchronization as well (was: We should move to
eliminate process synchronization via shared file system, and use a
process/service instead)
Changing the ticket name, since the goal has changed (and since the
implementation allows for flexibility in this dimension).

> Key: CONNECTORS-13
> URL: https://issues.apache.org/jira/browse/CONNECTORS-13
> Project: ManifoldCF
> Issue Type: Improvement
> Components: Framework core
> Affects Versions: ManifoldCF 0.1, ManifoldCF 0.2
> Reporter: Karl Wright
> Assignee: Karl Wright
> Fix For: ManifoldCF 1.5
>
>
> The current implementation relies on the file system to synchronize activity
> between various LCF processes. This has several downsides: first, it is
> possible to get the file system into a state that is corrupted (by killing
> processes); second, this limits the future ability to spread crawler workload
> over multiple machines.
> It should be reasonably straightforward, and probably more resilient, to
> introduce a "synchronization process", which all other LCF processes talk to
> in order to manage locks, shared data, and other synchronization activities.
