> MultiPartitionCacheTag relies on LinkedLists.
> A LinkedList object that holds e.g. 2 nodes consumes 112 bytes roughly in
> this composition:
> * 16 bytes for LinkedList object header
> * 8 bytes for referring head
> * 8 bytes for referring tail
> * 80 = 2 x (16 bytes for LinkedList$Node header, 3 x 8 bytes for referring
> prev, next, item)
> This is a lot, so I propose to replace LinkedList in MultiPartitionCacheTag
> with a simple String array. (For a similar scenario an array would take 16 +
> 8 + 2 x 8 = 40 bytes, as per header, count, and 2 references for our actual
> objects).
