1.2.2 The Large Stores

Large keys and associated data are not stored contiguous with the referring b-tree node, instead taking a new allocation unit. What large is depends on a built in constant and is something like 512 bytes. The default is half the store block size.

For their separate storage, large keys and data exhibit slower access times, lot slower if disk reading is involved.
