posix timestamp is a value of SECONDS since epoch. Druid takes the input as type of LONG, so the fraction is ignored. To keep the subsecond, you could turn the value into format of MILLISCONDS timestamp, that is 1591349534205 in your example. In practice, query granularity is widely used to utilize the roll-up functionality, which means there's no need to care about the exact timestamp of every record. Because of loss of subsecond, it's equivalent to set the query granularity to SECOND. So I think the loss is acceptable. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
