This article comes from http://my.oschina.net/noahxiao/blog/132277, personal storage use1. BackgroundWhen I use Hibernate to do object mapping, I always use the UUID to master the key. Since Hibernate's UUID needs to occupy 32-bit characters, it generally makes people feel more efficient and increase storage usage.When I looked at the company project, I found a better way to build the

The globally unique identifier (guid,globally unique Identifier) is also known as the UUID (universally unique Identifier).A GUID is a numeric identifier generated by the algorithm with a binary length of 128 bits. The format of the GUID is "Xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where X is a 32-bit hexadecimal number in the range of 0-9 or a-f. Ideally, no computer or computer cluster will generate two identical GUIDs.The total number of GUIDs reache

In the project, you need to change the original id to uuid, so you can directly use the uuid library in boost to generate a uuid. However, during the test, it was found that the program performance was severely degraded. In the past, 0.6 million pieces of data could be processed per minute, and only about 20 thousand pieces of data could be processed after

Three ways to view the UUID of a device are summarized below:1 Command view: Blkid2 file Views: Ls-l/dev/disk/by-uuid3 Command view: VOL_ID/DEV/SDA1The role and significance of UUID1: It's really the only signThe UUID provides a unique identification string for the storage device in the system, regardless of the type of device. If you start up in the system and use a drive letter mount, you may not find the
