nosql faster

In the era of cloud Sheng Xing, designing a large system not only considers traditional RDBMS, but also considers whether we want to use nosql products. One slice talked about this problem: Watch Extract several important points: 1. Considerations: rapid development, consistency, availability, latency, scale-out, cost, elasticity, manageability 2. There may be three major systems in the future: Analytics processing: complex offline adhoc repor

I like MySQL not only because of its simple use, but also because of its open source, plug-in engine, and better plug-in! From queue-type storage engine q4m (http://q4m.github.com/) to memcache UDF (http://hi.baidu.com/ytjwt/blog/item/5fc8303f226c542f71cf6c3c.html)NosqlMySQL, one day last year, a friend told me how good nosql performance is. I said that if I extract data like k/V-shaped data, suppose that I use a primary key to query a data, what do y

Distributed models of NoSQL DatabasesDistributed Model Single Server of NoSQL Database Distributed architecture is easy to deploy and easy to maintain when a server is fully competent;Shard features Each part of the data is stored on different servers of the cluster;For example, by letter: key values starting with a-g are stored on the first server, and keys starting with h-n are stored on the second server

Proficient in NoSQL come in and see what's the best solution for this situation? Site A's database has a very simple table xx, field: ID: Self-increment Key: The value is the only character Value: values are arbitrary strings Website B needs to read the data of XX table in this website a every day. What I'm doing now is: Whenever site a operates the XX table, it synchronizes the same operation to the MySQL database in remote server C. This way

MongoDB first release : 2009 Licensing mechanism : Open source whether SQL: no The most popular NoSQL database, but retains some of the SQL attributes, such as high performance on query and index large datasets, which is good for dynamic queries and index definitions to support Linux, OS X, and Windows, but the size of the database is limited to 2.5GB on 32-bit systems 6.

Most of the Web sites currently using MySQL use Memcache as the key-value cache. Although such a structure is extremely popular, there are many successful cases, but too dependent on memcache, virtually let memcache become the root cause of failure: Memcache Data Consistency problem: When the MySQL data changes, if not timely and effectively clean out the outdated data, will cause data inconsistency. This is not desirable in the Web2.0 era, which emphasizes immediacy. The avalanche effect afte

meaning of the array, but familiar with JS know, it is actually a non-linear pseudo array, subscript can be any number. Write arr[1000000] does not really request space to hold 1 million elements, but instead converts 1000000 to a corresponding hash value, which corresponds to a small piece of storage space, thus saving a lot of memory. For example, there are the following arrays: Copy Code code as follows: var arr = []; ARR[10] = 1000; ARR[20] = 2000; ARR[30] = 5000;
