Hi I need to set time to live programmatically for a table in DynamoDB via AWS Java SDK. Is it possible? I know that TTL feature is introduced recently - http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html
UPDATE: There is no special annotaion, but we can do it manually:
@DynamoDBAttribute
private long ttl;
and configure it as ttl in AWS - http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/time-to-live-ttl-how-to.html
long now = Instant.now().getEpochSecond(); // unix time
long ttl = 60 * 60 * 24; // 24 hours in sec
setTtl(ttl + now); // when object will be expired
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/time-to-live-ttl-how-to.html
public void function(final AmazonDynamoDB client, final String tableName, final String ttlField){
//table created now enabling TTL
final UpdateTimeToLiveRequest req = new UpdateTimeToLiveRequest();
req.setTableName(tableName);
final TimeToLiveSpecification ttlSpec = new TimeToLiveSpecification();
ttlSpec.setAttributeName(ttlField);
ttlSpec.setEnabled(true);
req.withTimeToLiveSpecification(ttlSpec);
client.updateTimeToLive(req);
}
