Hi,

Have you tried the ClusteredQuery feature introduced on [1]?

If you set index = LOCAL in the cache indexing config, only local entries
will be indexed
and then using a ClusteredQuery (see example in [2]), the query is executed
on all all nodes,
results are collected and merged before returning to the caller. Pagination
and Sorting should
be supported as well.
