It is always customary to compare with Oracle database when learning MySQL. When learning the storage structure of MySQL InnoDB, it is also unavoidable to compare with Oracle. Oracle's data storage is table space, segments, blocks, chunks, data files; MySQL InnoDB storage management is similar, but MySQL adds a concept of shared tablespace and stand-alone table space;First, the conceptShared tablespace: All

I've been learning about Hadoop recently, and today I've spent some time building a development environment and documenting it. First, learn about the running mode of Hadoop: Stand-alone mode (standalone)Stand-alone mode is the default mode for Hadoop. When Hadoop's source package was first decompressed, it was not abl

System environment required by the server 1. This article is to build zookeeper cluster under Linux (CentOS6.5), if you want to know how to build zookeeper cluster under Windows, you can go to another piece of my article Zookeeper+kafka cluster 2.ZooKeeper is written in the Java language, so its operating environment requires the support of the Java environment, and each CentOS installation in this article is JDK1.8. Zookeeper download Zookeeper's official download address is: http://www.apache.

The environment of this article is as follows:Operating system: CentOS 6 32-bitZookeeper version: 3.4.8 0.

Turncate table for Innodb-plugin InnoDB also shrinks the space.For tables that use stand-alone table spaces, no matter how they are deleted, the fragmentation of the tablespace does not affect performance too severely, and there is a chance to process it.5) The efficiency and performance of using exclusive tablespaces are a bit higher.Disadvantages:1) Single table increased too large, such as more than 100
