I am currently using Guava’s Table. In some cases I need something like:

Table<SomeMyKey, SomeMyKey, List<SomeMyDataClass>>

I am working with multi-dimensional data in Java, so it would be great to have something like a Table, but with more dimensions (not only rows and columns) and with collections for values. I understand that I cannot use it for a really huge amount of data, but with current amount of RAM, I think I should be able to maintain some thousands of elements…

I know about embedded Java DBs, but I do not want to have all the SQL overhead…
