WebLinear Hashing is a dynamically updateable disk-based index structure which implements a hashing scheme and which grows or shrinks one bucket at a time. The index is used to support exact match queries, i.e., find the record with a given key. Compared with the B+-tree index which also supports exact match queries (in logarithmic number of I/Os ... WebFeb 13, 2009 · Hash a file in chunks rather than feeding the entire file. Different approaches for different needs/purpose (all of the below or pick what ever applies): Hash only the entry name of all entries in the directory tree; Hash the file contents of all entries (leaving the meta like, inode number, ctime, atime, mtime, size, etc., you get the idea)
