Assuming that address 123 of a process stores 10, then the 123 address of the B process stores 20Then the two of them do not affect each other. But the value is real. The value is stored in physical memory. As shown in.According to the

Preface The previous article focused on the HDFS cache caching knowledge, this article continues to lead you to understand the HDFs memory storage related content. In HDFs, the target file cache for cacheadmin is stored in datanode memory. But in another case, the data can be stored in datanode memory. The

waste of memory, and of course, the cost of memory management is mainly to provide a unified management interface for different data types of Redis. The actual author also offers several ways to help us save memory as much as possible, which we'll discuss in detail later.　　Let's start with the analysis of the use of these five types of data and how to implement

. For a memory-based computing framework like SPARK, the GC problem is particularly prominent, it will cache a large amount of data in the JVM heap space, which is the data to be used in the calculation, the GC can not be removed, every time the full GC will do a global scan of the data, This is time consuming, and as the computational time increases and the heap memory data grows, the cost of the GC become

Let us first analyze the use of these five types of data and the internal implementation method.StringCommon Commands : SET,GET,DECR,INCR, Mset, Mget and so on.Scenario : String is the most common type of data, and normal Key-value storage can be categorized as such.implementation : String in the Redis int

Redis Common data typesThe most commonly used data types of Redis are the following five kinds:? String? Hash? List? Set? Sorted SetBefore describing these types of data, let's look at a diagram of how these different data types are described in Redis internal memory management:First, Redis internally uses a Redisobject object to represent all key and value,redisobject information as shown in: type represents what data type a value object is, encoding

serialization/deserialization and to retrieve the entire object when one of the information needs to be modified, and the modification operation requires concurrency protection. Introduce complex problems such as CAs.The second method is how many members of this user information object will be saved into the number of key-value, with the user id+ the name of the corresponding property as a unique identifier to obtain the value of the corresponding property, although the cost of serialization an
