Redis is an in-memory database that faces the risk of losing all data in case of a system failure. To address this issue, Redis provides persistence mechanisms to store the in-memory data on disk as files. Upon restart, Redis loads the persisted files to restore the original data. There are primarily three modes of Redis persistence: AOF (Append Only File), RDB (Redis DataBase), and a hybrid approach. In AOF mode, the AOF log file stores write operation commands in a text format. Each write command executed by Redis is appended to this log file. During data recovery, Redis replays the sequence of commands from the AOF log file. However, there can be redundant data in the AOF file, resulting in slow data recovery when performing full replay. In RDB mode, Redis writes binary data snapshots into an RDB file at specific time intervals. The RDB file is smaller and allows for faster data recovery compared to AOF; however, if any loss occurs during persistence in RDB mode, all in-memory data will be lost. The hybrid mode combines both approaches: persisting data using RDB and recording write operations using AOF during persistence period. After completing RDB persistence, incremental commands are appended to the file using AOF format. Consequently, this generates a file format containing complete RDB data along with incremental AOF data.
