1. share the same grid cache between the master and the slaves
Infinispan has a flat structure. The key has to contain:
- the index name
- the chunk name
Both with essentially be the unique identifier.
I suppose in this idea all indexes are stored in a one single grid.
What about one Infinispan grid per directory, similarly to
RAMDirectory or FSDirectory? IMHO it could make some simplifications
i.e. in metadata or key names.
Are there any Infinispan drawbacks to have a high number of caches
in the network? Sharing JGroups channels can help in that?
They already share JGroups channels and other "heavy" components
wherever possible. Its just that configuration becomes more of a
pain, etc.
When you say one cache per index, how do you define an index? Does 1
index mean all indexed data for a single java type? In which case
couldn't these scale up dynamically and potentially on-demand? No
wait - these are fixed in Hibernate Search on startup, correct?
