Redis has two persistence mechanisms (RDB and AOF) — have you considered these for reducing data loss window?

Redis indeed has two main persistence mechanisms: RDB (database snapshots) and AOF (command log). RDB creates periodic data snapshots, providing quick recovery but potentially leading to data loss for data created after the last snapshot. AOF logs every operation, minimizing data loss windows but possibly slowing down write operations and increasing file size.

To reduce the data loss window, AOF with the "appendfsync always" or "everysec" mode is often used — this balances performance and reliability. It is also possible to combine both mechanisms: RDB for fast recovery and AOF for minimizing data loss.

Example of AOF configuration in redis.conf:

appendonly yes
appendfsync everysec

Thus, the choice depends on recovery speed requirements and acceptable data loss levels.
