A key will lead me to a node. That node had range of keys each corresponding to an item.The key I get will point to an item. Let's say the item contains data, but given that the item size is limited the data may be spread across items nodes. How are all the data blocks where data from particular file is stored identified. Basically i want to know how are all the data blocks of a file are accessed and read?
