rabin fingerprint

The RABIN-KARP algorithm has good practicability for random string matching problems. It is based on the fingerprint mentality.The main string length is n mode string length is MAssume※① we can calculate a P's fingerprint at O (m) time F (P)※② if F (

AdtDefinition: A string that refers to a finite sequence of characters from an alphabet.Data structure: can be implemented by vectors or lists.Features: Compared to the general linear sequence, the string has more distinct characteristics: its

research on high performance data deduplication and detection and deletion technologyHere are some fragmentary data about the re-deletion of things, previously summarized, put on can communicate with you.The explosion of 1 data volumes brings new

Content-based variable-length chunking1, IntroductionData block detection technology is divided into fixed block detection technology (fixed-sized Partition, FSP), variable block detection technology (variable-sized Partition, VSP), sliding block

Content-Based variable-length block (CDC) technology can be used for variable-length blocks of files, and then for repetitive detection, which is widely used in deduplication systems. Later, Delta compression was performed on similar data blocks to
