Storage capacity: Is the maximum number of data that can be stored on the storage device, typically using kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), terabytes (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure.1Byte (equivalent to an English letter, a kanji account of 2 byte)1kb=2 (b=1024b); Quite a short story.1mb=2 (kb=1024kb=2) B; Quite the text of a short story1gb=2 (Ten) mb=1024mb=2 (B).

, spark shortened the sequencing time to 23 minutes when 206 EC2 nodes were used. This means that with one-tenth computing resources, Spark is 3 times times faster than MapReduce on the same sort of data!In addition, in the absence of an official PB sort comparison, we first pushed spark to the 1PB data (10 trillion records) sort. The result of this test is that with 190 nodes, the workload is completed in less than 4 hours, as well as the 16-hour record of using 3800 consoles before Yahoo. At t

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB? Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese character requires two bytes of storage space,

the schema to 4 petabyte (PTs). As a reference, the previous version of Aix can only handle files with a total of 64GB, so Aix 5L has a huge increase in storage. In addition, the operating system currently supports systems with 32 processors and 256GB RAM. Security has always been a proud area of AIX, and the same proof can be obtained in this version. AIX is the first 64-bit UNIX operating system to meet the E3/F-C2 and virtual personal Network (VP

, COUCHDB is another document-oriented database that stores data in JSON format. It is compatible with acid, like MongoDB, COUCHDB can also be used to store the data and content of the website, as well as provide caching and so on. You can run a MapReduce query on Couchdb via JavaScript. In addition, COUCHDB provides a very convenient web-based management console. It is ideal for Web applications.4. hypertableHypertable imitates Google's bigtable database system. Hypertable's creator will "becom

biggest selling point for MongoDB is a simple development process and the flexibility to handle modern data from mobile, social, and Web applications. MongoDB ushered in the 2.6 release this May, which further simplifies management, strengthens security, and improves analytics. This version also increases scalability to narrow this gap with rivals such as Cassandra, Couchbase, and Riak. However, in contrast to scalability, MongoDB is able to provide excellent processing speed, ease of developme

table pointer. In VC 2005, the following output is displayed: Petabyte: 00480010CA: 00480018 The difference between the two addresses is 8 bytes. The addresses of the two objects are not equal because of the relationship between the virtual function table pointers. The pointer of the virtual function table usually occupies 4 Bytes. In the output result, the difference value is related to the object layout, that is, it is also related to the object a
