Benefits of MySQL using partitioned tables:
1, you can put some of the data in the collation of a partition, you can reduce the number of server check data to speed up the query.2, easy maintenance, delete the old data by deleting the partition.3, partition data can be distributed to different physical locations, can do distributed effective use of multiple hard
because the MBR partition table has a maximum addressable storage space of only 2Tb (2 x512 bytes). Therefore, in the case of large hard disks, the MBR partitioning method is gradually replaced by the GPT partition table. The following is an experiment for installing red Hat Enterprise Linux 6.4 on a 8T hard drive. Lab Preparation ToolsWorkstation 8.x or laterRed Hat Enterprise Linux 6.4 CDThe workstion use

MySQL specifies the path of each partition and mysql PartitionIntroduction
You can specify the storage path for each partition of a partitioned table. For an innodb Storage engine table, you can only specify the data path, because the data and indexes are stored in one file, for the MYISAM storage engine, you can specify data files and index files respectively. Generally, only the RANGE, LIST partitions, an
In SQL Server, data archiving of super Large tables, using SELECT and Delete commands is very CPU-intensive and disk space, SQL Server must record the corresponding number of transaction logs, and using the switch operation to archive partition table old data, very efficient, The switch operation does not move the data, only the replacement of the metadata, so the time to perform the partition switching ope

In the previous section we described how to create and use a partitioned table, with an example of placing data from different years in different physical partitions. The specific partitioning method is:1th Small table: Data prior to 2010-1-1 (not including 2010-1-1).2nd Small table: Data from 2010-1-1 (including 2010-1-1) to 2010-12-31.3rd Small table: Data from 2011-1-1 (including 2011-1-1) to 2011-12-31.4th Small table: Data from 2012-1-1 (including 2012-1-1) to 2012-12-31.5th small table: Da

Several categories of partitioned tables:1, Range (range) partitionIs the application of a wide range of table partitioning method, which is the range of the value of the column as a partitioning of the conditions, the record is stored in the column value of theRange partition. For example, according to the time division, 2012 1 quarters of data into a

Knowledge Point Analysis:
When you install a Windows system, it often occurs when you choose to install the partition interface prompt, "Setup cannot locate an existing system partition, or create a new system partition", sometimes by removing all of the existing partitions, the repartition can be resolved. In some cases (such as the addition of SSD, new hard di

Using the BIOS boot partition is not the only way to resolve a problem based on the traditional BIOS but using the GPT format disk, but complex boot loader su

In the document, the partition's locking operation is performed before performing some operations on the interval partition.
Unlike other types of partitioned tables, the partition of the interval partition table does not necessarily exist, and whether the partition exists has to do with the range of data that the use

MyD data has reached 10G, it is inevitable that the reading efficiency is very low, this time we can use to divide the data into several tables to solve the problem.Mode one: Through the business logic according to the size of the data by id%10 this to be divided into user1,user2,user3 and so on, but this will have a lot of problems we need to maintain such a hash relationship, And every time we read the data
