From: http://rdc.taobao.com/team/jm/archives/951 The join of secondary indexes and indexes is a basic feature that most business systems require the storage engine to provide. RDBMS has long supported it, and the nosql camp is exploring the best solution that suits its own characteristics.This article will use hbase as an object to discuss how to build secondary indexes and implement index join Based on hbase. At the end of this article, we will also list the currently known versions including

space can be directly accessed. Of course, this is related to the number of slots on the motherboard and the maximum size of memory supported by each slot. Data Bus width ). The data bus is responsible for the data traffic of the entire system. The data bus width determines the amount of data transmitted between the CPU and the second-level high-speed cache, memory, and input/output devices. Co-processor (Digital coprocessor ). There is no built-in

register (GDTR), Interrupt Descriptor Table register (idtr), Local Descriptor Table register (ldtr), and task Status Register.(TR ). The system table register is used to manage four system tables in the protection mode. It is also called the protection mode register because it can only be used in the protection mode. This article introduces the description of the appendix. V. Control registers There are four control registers of 80386, CR1 is retained for later use, and a CR4 is added starting

IntroductionARM7 is a member of the 32-bit general-purpose microprocessor arm (advanced RISC machines) family, with relatively low powersource consumption and a good price/performance ratio,based on RISC structure, instruction set and related decoding mechanism and micro-programcontrol of the complex instruction system is relatively simple compared to the computer,This allows it to have higher command processing power and real-timeinterrupt response capability. The instruction set consists of 11

To crawl remote Web content via a local agent, the code is as follows: array( 'proxy'=>'tcp://192.168.1.108:8087', 'request_fulluri '=>true, "method" => "GET", "timeout" => 2, ),);$context = stream_context_create($options);$fp = stream_socket_client("tcp://www.bigxu.com:80", $errno, $errstr, 30,STREAM_CLIENT_CONNECT,$context);// print_r(stream_context_get_options($fp)); exit;if (!$fp) { echo "$errstr ($errno

Under Windows, the Android phone is very simple to connect to a PC, but when I switch to Ubuntu, I see a line in the target list. N/a unknown "similar to the content of such a line, the PC can not correctly identify the phone, by looking for relevant information, the relevant settings, found that can connect the PC, so this record down, for later use.1, find the phone USB information (ID)Method: First unplug the phone to connect to the PC's USB cable, then view the USB device information, plug i

active). If the current task uses a coprocessor, its context is saved. The assembly instruction CLTs is used to clear the Task/interchange (TS) flag in the control register CR0. Each time a task switch occurs, the CPU sets the flag. This flag is used to manage the math coprocessor: if//The flag is set, then each ESC instruction will be captured. If the Coprocessor
