Dynamically set TTL on an individual record

[ajeetdsouza]

Hi, I'm trying to set a TTL when saving an individual record, but the AeroMapper.save() function overrides it. How can I save a record with a different TTL than the default?

This is what I'm trying to do:

WritePolicy policy = new WritePolicy(client.writePolicyDefault);
policy.expiration = 10;
mapper.save(policy, shortLink);

This is the offending code:

java-object-mapper/src/main/java/com/aerospike/mapper/tools/AeroMapper.java

Lines 229 to 231 in a0d1164

	if (ttl != null) {
	writePolicy.expiration = ttl;
	}

Is the TTL you're setting ignored or are you getting an error message (and if so, which)?

Also, did you enable expiration on the server side by setting the nsup-period in your namespace configuration?

See here for some more details:

By default, expiration and eviction are not enabled.

@realmgic the TTL I'm setting is getting ignored, there is no error message generated.

The reason for this is the 3 lines of code I linked above -- they are taking the TTL from the annotated class and using that to overwrite the TTL on the WritePolicy that I have manually passed.

Got it, @ajeetdsouza - sorry I couldn't be more helpful
