ZoieSegmentReader, let's take a look at the real-time search mechanism when documents are updated. (1) when the system was initially started, it was in Sleeping state. At this time, the memory index was empty and there were documents A, B, and C on the hard disk index. (2) When file B is updated in Sleeping state, file B enters the memory index, and disk index

this year. Some experts said that Microsoft's launch of real-time search technology is likely to be to suppress Microsoft's Bing search in search traffic in the recent rise in the momentum. Like other synthetic searches, Google picks up real-time search results in its comprehensive search results and determines the e

Although the data in DW is also subject-oriented and integrated, the data is generally not modified, therefore, the differences between ODS and DW mainly reflect data variability.And current. 　　2.2 Real-Time OLAP ODS is mainly generated to meet the needs of enterprise-level global applications, and its applications are mainly used for

What is Iftop?The iftop is a real-time traffic monitoring tool similar to top.Official website: http://www.ex-parrot.com/~pdw/iftop/Second, what is the use of iftop?Iftop can be used to monitor the real-time traffic of the network card (can specify the network segment), reverse resolution of IP, display port informatio

, however, the/proc/stat file also has a refresh precision. The refresh precision is for each clock interruption period, that is, the data in the/proc/stat file can be updated once per tick at the fastest, when a clock is interrupted, the system checks the processes running on the current CPU. for user-State processes, a tick is added to the user-state record data in the kernel_stat data member. For kernel-State processes, the number of kernel-State member records increases. The top usage is der

Board. The test proves that the operation of the operating system in DSP chip can be tms320c6713, the reliability is guaranteed, and the real-time performance is greatly improved. At the same time, the porting method introduced in this paper has a strong universality in the same kind of DSP architecture processor, and it also has some instructive meanings to the

How can I store real-time webpage data in a file and use php for real-time webpage? if the file changes, I will immediately update the current webpage. how can I achieve this? The previous idea was to make a round-robin request in js every second. if the file changes, it will be reloaded. I think this is not good -----

For example, if a multi-channel speech stream is merged into a single-channel speech stream, the SSRC of each original audio channel is listed here.RTCP (real time contorl Protocol) RTCP is responsible for managing the communication qualit

Analysis of the Reason Why Hadoop is not suitable for processing Real-time Data1. Overview Hadoop has been recognized as the undisputed king in the big data analysis field. It focuses on batch processing. This model is sufficient for many cases (for example, creating an index for a webpage), but there are other use models that require
