TTL with spring-cloud-aws-starter-dynamodb DynamoDbTemplate

[huehnerlady]

Hi,

I am currently migrating our service to spring-boot 3 and saw the changes made here. I saw there is a DynamoDbTemplate and the usage looks quite nice an simple in comparison to our use of the Table object before, but so far I could not find out how to set a ttl for the items in a table. In the properties provided all I can see is a connection-ttl.

Can anybody maybe assist with an example?

Lately I was thinking about this as well. TTL of an item is based on an items attribute of your choice.

For example you can create an attribute called expirationDate with data type long (must be epoch seconds) and populate it yourself. Then in the aws console you tell dynamodb that expirationDate is your ttl attribute and it will take care of the rest.
