+ <p>
+ The Block Disk Cache stores cached values on
disk. Like
+ the Indexed Disk Cache, the Block Disk Cache
keeps the
+ keys in memory. The Block Disk Cache stores the
values
+ in a group of fixed size blocks, whereas the
Indexed
+ Disk Cache writes items to disk in one chunk.
+ </p>
+ <p>
+ The Block Disk Cache has advantages over the
normal
+ indexed model for regions where the size of the
items
+ varies. Since all the blocks are the same size,
the
+ recycle bin is very simple. It is just a list
of block
+ numbers. Also, the Block Disk Cache will never
need to
+ be optimized. Once the maximum number of keys is
+ reached, blocks will be reused.
