How AOF Works?

The Append-Only File (AOF) in Redis is a persistence mechanism that logs every write operation to a file in sequential order, ensuring data durability. Each command is appended to the end of the AOF file, which Redis can replay to rebuild the dataset in case of a restart. The AOF file can grow over time, so Redis provides an automatic background process called AOF rewrite to create a compact version by eliminating redundant commands. AOF is generally safer than the default RDB snapshotting, as it provides finer granularity for data recovery and minimizes the potential for data loss.
