Yes, Redis can support persistence, although it's primarily known as an in-memory data store. There are two main mechanisms for achieving this:
# To enable RDB persistence in Redis configuration save 900 1 # save the DB if at least 1 key changes in 900 seconds dbfilename dump.rdb dir /path/to/your/data
# To enable AOF persistence in Redis configuration appendonly yes appendfilename "appendonly.aof"
Redis also allows you to use both RDB and AOF. If configured this way, Redis will use the AOF file to load the dataset at startup, and will continue to persist data using both RDB and AOF.
Keep in mind that configuring Redis for persistence has implications for memory usage and performance. Therefore, choose based on what fits your application needs best.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
