Interceptor that allows invocations only when cluster is formed of N nodes
--------------------------------------------------------------------------
Key: ISPN-928
URL:
https://issues.jboss.org/browse/ISPN-928
Project: Infinispan
Issue Type: Feature Request
Components: Configuration, RPC
Reporter: Galder Zamarreño
Assignee: Galder Zamarreño
Fix For: 5.0.0.BETA1, 5.0.0.Final
Following from
https://github.com/pmuir/infinispan-examples/commit/f5d090092fa7b3660025b...
It'd be great to have an configurable StrictCluster interceptor in Infinispan which
would basically make all invocations wait until the cluster of N nodes has been formed. I
think it'd be a great addition and would allow clients to verify whether the cluster
actually forms without the need to verify whether data replicates...etc.
In principle, the configuration would be at the CacheManager, i.e.:
<transport strictNumMembers="4"... />
However, it could also be useful to configure it at the cache level. So, could maybe want
to do this: I want cache X to allow invocations the moment I have 2 nodes (in spite of the
cluster being formed of 4 noes), whereas I want cache Y to allow invocations once I have 3
nodes.
Apart from an strict number of nodes, you could have a minimum number of nodes: allow
invocations once I have 4 or more nodes. The strict value could still be useful to make
sure intrusive machines don't get into the cluster, i.e. I expect 4 nodes in the
cluster and if I have 5, something is wrong.
I think it's an interesting concept that would get rid of cluster validation code in
examples and RadarGun.
