Available since: 7.0.0

Time complexity: O(N) where N is the number of functions

ACL categories: @slow @scripting

Return the serialized payload of loaded libraries. You can restore the serialized payload later with the FUNCTION RESTORE command.

The following example shows how to dump loaded libraries using FUNCTION DUMP and then it calls FUNCTION FLUSH deletes all the libraries. Then, it restores the original libraries from the serialized payload with FUNCTION RESTORE.

redis> FUNCTION DUMP
"\xf6\x05mylib\x03LUA\x00\xc3@D@J\x1aredis.register_function('my@\x0b\x02', @\x06`\x12\x11keys, args) return`\x0c\a[1] end)\n\x00@\n)\x11\xc8|\x9b\xe4"
redis> FUNCTION FLUSH
OK
redis> FUNCTION RESTORE "\xf6\x05mylib\x03LUA\x00\xc3@D@J\x1aredis.register_function('my@\x0b\x02', @\x06`\x12\x11keys, args) return`\x0c\a[1] end)\n\x00@\n)\x11\xc8|\x9b\xe4"
OK
