WebApr 9, 2024 · * In Extendible Hashing we map a key to a directory index * using the following hash + mask function. * * DirectoryIndex = Hash(key) & GLOBAL_DEPTH_MASK * * where GLOBAL_DEPTH_MASK is a mask with exactly GLOBAL_DEPTH 1's from LSB * upwards. For example, global depth 3 corresponds to 0x00000007 in a 32-bit WebLezione III - DMI
WebExtendible hashing is a new access technique, in which the user is guaranteed no more than two page faults to locate the data associated with a given unique identifier, or key. … WebIt uses the lowest-bits for the hash function. That is, records in a bucket of local depth d agree on their rightmost d bits. For example, key 4 (100) and key 12 (1100) agree on their rightmost 3 bits (100) (a) Draw the extendible hashing of the resulting directory after inserting keys 2, 20, 21, 12, 31, 30 , 3 , 13 in order.

What is the probability that an overflowing bin should treated retroactively? "Treated retroactively" means that all the records of the bin should be transferred to one of two new bins that are created. I created the bins for N = 2,3,4 , but I can't find a pattern.

Because of the hierarchical nature of the system, re-hashing is an incremental operation (done one bucket at a time, as needed). This means that time-sensitive applications are less affected by table growth than by standard full-table rehashes. Extendible hashing was described by Ronald Fagin in 1979.
