crc64

View the RDB file structure, found that the last 8 bytes is the CRC64 checksum, from the beginning of the file to the 8-byte check code before the FF End Code (inclusive), after the CRC64 check calculation found that the last 8 bytes is the

Because of the platform access, the platform provides a string key as the user ID, and distributed is required, so the user ID cannot be incremental with the previous database, therefore, crc64 is used to generate uint64_t as the user ID, which is

Redis supports two persistence policies: snapshot and commandlog. The former is implemented by periodically writing the current Memory Data snapshot into the RDB file; the latter is implemented by recording the write operations received by the Redis

Redis has problems with data errors when it comes to network transmissions and RDB backups, so it uses data validation. Includes a validation algorithm that uses the CRC64. The CRC test principle is actually the addition of an R-bit binary test code

Today began to study the Redis source code of some of the tools of the implementation, tool class in any language, the implementation of the principle of the algorithm should be the same, so you can take this opportunity to learn some of the more

From today on, I will start learning redis source code. The redis code is relatively small and very suitable for learning. It is a very good learning material, it looks like about 100 files, which are written in C language. I hope I can finally get

This is a creation in Article, where the information may have evolved or changed. As a go language layman, this time just using Go to implement a distributed indexing system simulation experiment, this article summarizes the implementation process
