I’m suffering a problem about flattenSpec using tranquility.
I wonder, does tranquility know nested timestamp using flattenSpec ?
I’m using druid 0.9.0 stable version, and tranquility core java api.
I searched through this Druid User group, just a little subject talk about flattenSpec.
In this subject, it seems that using nested timestamp may ok with tranquility.
But this subject says, the druid.io doc is out-of-date, and it should replace ‘nested’ with ‘path’.
When I used nested timestamp in tranquility, it dropped all messages which I think the reason of is that tranquility doesn’t recognize the nested timestamp.
