A complete example of a consistent hash algorithm implemented by PHP, a consistent hashing algorithm In this paper, we describe the consistent hashing algorithm implemented by PHP. Share to everyone for your reference, as follows: I hope this article is helpful to you in PHP programming. http://www.bkjia.com/PHPjc/1071395.html www.bkjia.com true http://www.bkj

A distributed hash (DHT) implementation algorithm, proposed by MIT in 1997, was designed to address hot spot problems in the Internet, with a similar intent to carp. The consistent hash corrects the problem caused by the simple hashing algorithm used by carp, so that distributed hashing (DHT) can be really applied in the peer-to-peer environment. The consistency hash algorithm proposes four definitions for determining the good or bad hash algorithm i

possible for a particular node to be mapped to different content by different terminals. As with dispersion, this situation should also be avoided, so a good hashing algorithm should be able to minimize the load on the nodes. In a distributed cluster system, the increase or removal of machines or machine failure is often the case, if the use of simple modulo hashing algorithm, the machine changes the calculation of the algorithm to be re-modified, the location of the stored objects must be

The traditional distributed algorithmBefore understanding the Redis distributed algorithm, it is better to understand the application scenario in the cache, after understanding the application scenario, then to understand the consistency hashing algorithm, it is much easier, and more can reflect the advantages of a consistent hashing algorithm, then we first describe this classic distributed cache application scenario.Scenario Description:Assuming we

Note: When backing up a database, do not back up redo logs. 1.1 Consistent backup Concept: Database Consistency backup refers to the method for backing up all data files and control files after the database is disabled. When the SHUTDOWN command is used to shut down the database normally, the c

The design goal was to solve the hot spot issue on the Internet. The original intention was very similar to carp. Consistent hash corrected the problems caused by the simple hash algorithm used by carp, so that DHT can be truly applied in P2P environments. However,

In actual work, we often look at the execution plan of an SQL statement, for example: After sqlplus uses the set autotrace on command, the execution plan is shown as follows: SQL> set autotrace on SQL> select count (*) from EMP; Count (*)----------12 Execution Plan----------------------------------------------------------0 SELECT statement optimizer = choose1 0 sort (aggregate)2 1 Table Access (full) of 'emp'Statistics----------------------------------------------------------0 recursive
