About Redis

  • Redis is similar to memcached and also belongs to K-V data storage
  • Redis official website Redis.io
  • Supports more value types, in addition to string, hash, list (linked list), sets (set), and sorted sets (ordered information)
  • Redis uses two file formats: Full data (RDB) and incremental requests (AOF). The full data format is to write the in-memory data to disk to facilitate the next read of the file to load. The incremental request file serializes the in-memory data into an operation request and is used to read the file for replay to get the data, similar to MySQL binblog.
  • Redis's storage is divided into memory storage, disk storage, and log file three parts.
