Memcached Performance TestingMemcached as a memory Key-value storage container has excellent performance, but in the last use of the discovery of a large number of data loss occurred, resulting in the function of the cache basically disappeared. The specific detection methods are as follows: Test hit ratioDetection hit rate is the most basic, most macroscopic way, using Telnet to connect to the memcached server, and then execute the stats command to s

depend on the recovery model of the database. Let's take a look at the examples below: --Paragraph restore: the database is corrupted in scope, and we have to restore the entire database across multiple data files and even across filegroups. -At this point, if the database is particularly large, the database recovery time will be very long. However, we can use the paragraph restore provided by SQL Server to recover the database gradually. --First back up the tail log: Backup log [Adventur

very good coordination to achieve some good application. For example, through the Regionprops function to determine the characteristics of each block (such as center, area, etc.) STATS = Regionprops (l,properties) measures a set of properties for each labeled RE Gion in the label Matrix L. 2, Regionprops: The purpose is get the properties of region, the function used to measure the properties of the image region. Syntax:

a syntax similar to the SET command, but includes an extra value: The extra value returned by the gets. Note the following interactions that use the CAS command: Set userId 0 0 5 55555 STORED gets userId 6 55555 END 6 33333 STORED As you can see, I call the gets command with an extra integer value 6来, and the operation runs in a very sequential order. Now let's take a look at the series of commands in Listing 7: Listing 7. CAS commands with older version indicators
