eviction, clustering, and expected behavior

[shulok]

Can't find a definitive answer, and I'm not seeing what I would expect...

If you have eviction enabled and you are clustered: if server A touches node /x before eviction times out, should server B evict the node since he hasn't touched it within the interval? This is what I'm seeing, but I would expect that if anyone in the cluster touches a node within the eviction interval, no server should evict it. Am I wrong, or is this a configuration issue?

Thanks,
Thom

You're wrong. :-) Eviction is managed per node. A write operation on server A will affect the eviction calculation on B (since the write replicates to B). But a read on A does not affect the calculation on B, since B knows nothing about a read on A -- there's no message sent around the cluster saying "A just read /x" as that would add too much overhead.

Nuts, I hate when that happens. :-)

Thanks for the prompt response, Brian.
