Karl Wright commented on CONNECTORS-781:
----------------------------------------
Using the database instead of an in-memory structure for document priority
assignment with PostgreSQL seems to markedly slow down crawling, at first
glance, as I feared. The RSS load test took 246 minutes to run on my test
machine. I remember times significantly less than that for the baseline;
confirming that now.
> Fault-Tolerant Setup for ManifoldCF Agent.
> ------------------------------------------
>
> Key: CONNECTORS-781
> URL: https://issues.apache.org/jira/browse/CONNECTORS-781
> Project: ManifoldCF
> Issue Type: Improvement
> Components: Framework agents process, Framework core, Framework
> crawler agent
> Affects Versions: ManifoldCF 1.5
> Reporter: Swami Rajamohan
> Assignee: Karl Wright
> Labels: agents, crawler, fault-tolerance
> Fix For: ManifoldCF 1.5
>
>
> It should be possible to setup ManifoldCF as a Fault-Tolerant infrastructure.
> The Agent component of ManifoldCF should support multiple instances of an
> agent crawling against a single crawl store, to be able to both distribute
> (share) the crawl load as well as to be able to pick up a request that gets
> abruptly terminated due to either partitioning of the instance/failure of the
> instance itself.
> Since there is a proposal to move to a store like Voldemort, it would be nice
> to be able to have a fault tolerant infrastructure.
