How to set ttl of as_record when read

Liu_Ld · February 4, 2015, 8:12am

In file “as_record.h”, it says “Note that the TTL value will be employed ONLY on write/update calls.”

But I need to reset record’ ttl when read it too. I have two options now :

Do a read-operation and then do another update-operation
Build a UDF function to read and reset ttl

Is there a simpler way to match my application?

Another option is to use the aerospike_key_operate() function, building up two operators, “touch” and “read”.
