RDB Dump on Sigterm when AOF is enabled

[davissp14]

Out of curiosity, why does Redis work to dump an RDB on SIGTERM when AOF is also enabled? Is there value to this operation given the AOF file is used on boot?

Hi @davissp14,

• By default redis only saves to DB snapshot file.
• If we configure redis only with AOF (appendonly yes), it writes only to AOF file.
• And If we configure redis with AOF and Snapshotting (save x y), it writes to both AOF and DB snapshot and when SIGTERM is received it completes the write to both AOF file and DB snapshot to keep both of them up to date.
