PHP data compression, encryption and decryption (pack, unpack), and data compression unpack Data is frequently exchanged in network communication and file storage. To reduce network communication traffic, file storage size, and encrypted communication rules, two-way encrypti

SQL Server focuses on optimization of Stored Procedure performance, data compression, and page compression to improve IO performance (I ). Preface The SQL Server basic series is not over yet, And the last point is not written, and will continue later. Some school friends asked me when I began to write the SQL Server performance series. It may take some time to wa

Programmer interview book-Dual-Link Table of Data Structure, programmer interview book 1 #include L Implementation of double-stranded tables with data structures? Double-linked table1. Double Linked List (Doubly Linked List)The dual (forward) linked list has two different links, that is, in addition to storing the n

efficient approach is to use a data structure that is efficient in searching performance instead of sliding windows.LZ77 has a better compression ratio than Huffman coding, but LZ77 takes a considerable amount of time during the compression process. If the forward buffer contains a, B, and D then the buffer contains the phrase {(A), (a,b) (A,B,D)}If the sliding

spatial requirements of a transaction are determined by whether the compression method is online (on or OFF) and the recovery model of the database. When Sort_in_tempdb=on (recommended on), in order to implement concurrent DML operations, the internal structure of index is mapping in TEMPDB to map the relationship between the old book sign and the new bookmark. For versioned storage, the usage of tempdb is

Hello everyone, my name is Wang Benben. In the past few months, due to work needs, I have been paying more attention to the current situation and development of data compression technology, and have personally implemented several data compression modules. OnceIn the process, I found that Chinese technical materials in

, in addition to skipping the cost of traversal, also skips understanding the process of compressing these compressed blocks, thus saving the CPU.Merging with BitsetBitset is a very intuitive data structure that corresponds to posting list such as:[1,3,4,7,10]The corresponding Bitset is:[1,0,1,1,0,0,1,0,0,1]Each document is sorted by the document ID and corresponds to one bit. The Bitset itself has the feature of
