For example, Memcached has a service address of 192.168.4.86:11211 and can telnet to the service port:Telnet 192.168.4.86 11211If the connection succeeds, you can use some of the following commands: Stats comm

, obviously in order to get faster speed, sometimes we have to space to change time. That is to say, memcached will pre-allocate memory, yes, memcached allocating memory is called allocator, first of all, there are 3 concepts:1 Slab2 page3 Chunkexplain that, in general, a memcahced process will be in advance to divide themselves into several slab, each slab under a number of page, each page under a number of chunk, if we think of these 3 strokes as object, this is the two one-to-many relationshi

process will be in advance to divide themselves into several slab, each slab under a number of page, each page under a number of chunk, if we think of these 3 strokes as object, this is the two one-to-many relationship. In general, the number of slab is limited, a few, more than 10, or dozens of, which is related to the memory of the process configuration. And each slab under the page by default is 1m, that is, if a slab consumes 100m of memory, then by default this slab has the number of page

Monitor contexts (watcher context). Prototypes of other callback functionsThere are several callback functions in Zookeeper that are used in asynchronous APIs (functions that typically start with zoo_a*), which are divided into the following types of callback functions that handle the return value type of an asynchronous function: Handling a callback function that returns a void type, handling a callback function that returns a STAT s

Brief introductionThe Shutil module provides advanced operations for a large number of files. Specifically for file copying and deletion, the main functions are directory and file operations, as well as compression operations. The operation of a single file can also be found in the OS module.Note Even a higher-level file copy function (Shutil.copy (), shutil.copy2 ()) cannot copy all of the file's metadata. This means that the owner and group of the file and the access control list are lost on t

categories: persistent node and temporary node . Persistent Node The so-called persistent node is that once the Znode is created, the Znode will be kept on zookeeper unless the active Znode removal operation is initiated. Temporary Node The lifecycle of the temporary node is bound to the client session, and once the client session is invalidated, all temporary nodes created by the client are removed. In addition, zookeeper allows users to add a special attribute for each node: sequential. Once
