Hmmm, why would you use an in memory database with Infinispan, which is an in memory data grid?
Thank you Galder, for the reply.
The HSQLDB is used in file mode. This is a trial to use a better performing file based persistence for infinispan. The application we are building cannot afford the cost of Berkley DB and the performance overhead of JDBM. During evaluation of HSQLDB, I came across the link posted above.
BTW, is there a better LGPL alternative for JDBM / File based cache store?
