How to update TTL of a specific Aerospike record without using UDFs?

Question

I have an application which needs to be able to point to any aerospike database based on the configuration file, from what I understand, using a UDF invovles the .lua file to be installed on the aerospike server in the first place which I cannot guarantee. Is there a simple way to update the metadata of a specific aerospike record using a Java client?

Answer 1

You would use the touch operation to modify only the meta data:

An example can be found here:
