1. Server space stabilityWhen talking about the stability of server space, to be honest, I am very angry. Let's take my own case as an example. The golden abacus cashback website is a professional campus Taobao cashback site. It started to work in March 7, and everything went fine. In April 1, I couldn't log on. I was naive to think that there was a problem with the rest of the space provider staff. The phone call stops and qq does not return. In this way, I ran the space service provide

There are no tricks to do the station. maybe someone else has it, but I won't, so I cannot teach you how to take shortcuts. I can only do things right now, and then make some small achievements and share them with you here. To increase the website indexing volume, there are only three things: attracting search engine spider to your website; making search engines crawl your webpage smoothly; and making search engine spider feel that your webpage is use

be after a.m. from the perspective of long cycle. there will be two relatively large updates each month. most people agree with this statement on the 11th and 26th/28th. Google update time: Prediction: recording time: 1st days after the update; Update Time: updated every seven days (with a low ranking impact); major update time: updated every month (with a high ranking impact ), the PR value is updated once every three months (updated on January 1, September 20, and so on), because the t

to index. 4. Create an appropriate index 5. Use a fixed-length field to accelerate the process. (8) Indexing principles 1. Use indexes reasonably One table can only use one index in one query. The explain statement is used to check the operation of the optimization program. Use analyze to help the optimizer make more accurate predictions on the index usage. 2. Indexes should be created on the Data columns involved in operations such as se

I did a test in two weeks. Maybe many Webmasters have done similar research. Two weeks ago, I updated the Forum at least two original articles with over 500 words each day. Baidu has taken effect on my new post for about three days. They all say that Baidu prefers high-frequency updates and excellent originality, which undoubtedly proves this result. During this period, Baidu's traffic to the Forum was at least 100 or 200 IP addresses. I started to stop the update until January 1, November 16

Oracle implements function-based indexing Use Cases:When a query runs slowly. By checking the where clause, it is found that the SQL lower function is applied to a column, and the lower function prevents the use of existing indexes on the column. You want to create a function-based index to support this query, as shown below: SQL> select index_name, column_name from user_ind_columns where table_name = 't1 '; INDEX_NAME COLUMN_NAME---------------------

As I needed to train my colleagues on database indexing knowledge, I collected and sorted out this series of blogs. This is a summary of index knowledge. After summing up, I found that many vague concepts were much clearer in the past. Whether it is cached data information or physically saved information, their basic unit is data pages. Therefore, understanding data pages is the most basic knowledge point. This blog introduces some basic knowledge abo

When the indexing algorithm determines the index speed of Lucene, three parameters are most affected: mergefactor, maxmergedocs, and rambuffersizemb in indexwriter. These parameters are nothing more than controlling the internal and external memory exchanges and the frequency of index merging to increase the index speed. Of course, these parameters must be set flexibly according to hardware conditions. Maxmergedocs This parameter determines the number

non indexed, but creating a composite index on the area, the age two column can be more efficient. If we create a composite index (area, age, salary), it's actually equivalent to creating (Area,age,salary), (Area,age), (area) Three indexes, which is called the best left prefix feature. So when we create a composite index, we should place the columns that are most commonly used as constraints to the left, decreasing in descending order. 3, the index does not contain columns with null valuesThis

oversized files that they generate during page crawls and indexing. In particular, GFS can save a lot of time spent on system management.In 2004, they started to implement an open source implementation, the Nutch Distributed File System NDFs.In 2004, Google published a paper to introduce their mapreduce system to the world.At the beginning of 2005, Nutch's developers implemented a mapreduce system on Nutch, and all the major algorithms of Nutch were
