Edge TTL not working for Janusgraph with Bigtable

I'm creating edges with TTL of 30 seconds but I can see those edges aren't getting deleted. I'm using Janusgraph 0.6.1 and I'm able to see a TTL of 30 seconds when I do gmt.getTTL(mgmt.getEdgeLabel("ttlTest3")).getSeconds(). What can be the cause of this?

TTL in nonstatic vertex labels Janusgraph

I wanted to set a TTL in some vertices but I don't want those vertices to be static. How can I implement TTL in Janusgraph since I cannot use the pre existing implementation of TTL because it requires the vertices to be static?

Question about conversion of datetime to epoch

Hii, I wanted to know if there's a way to convert datetime stored in a node to epoch, without using lambdas because I don't want to compromise on performance. The reason why I'm doing this is to figure out the time difference between two timestamp values in nodes, something like this : -


g.V().has("Customer",'customerId', 'abc').out()
    .has("Attempt", "eventTimestamp", between(datetime(LocalDateTime.parse('2023-03-01T00:00:00').minusDays(15).toString()),
                                              datetime(LocalDateTime.parse('2023-03-01T00:00:00').minusDays(1).toString())))
    .as('a').values('nodeCreatedAt').in().hasLabel('Device').values('nodeCreatedAt').as('b')
    .math('a - b').by('nodeCreatedAt')
