LASTSAVE
Syntax
LASTSAVE
Time complexity: O(1)
Return the UNIX TIME of the last DB save executed with success.
A client may check if a BGSAVE
command succeeded reading the LASTSAVE
value,
then issuing a BGSAVE
command and checking at regular intervals every N
seconds if LASTSAVE
changed. Dragonfly considers the database saved successfully at startup.
Return
Integer reply: an UNIX time stamp.
