Good Morning! I am a little stuck figuring out how to handle custom time formats with nanosecond precision. The data that I am currently trying to ingest has two different time formats: 1629480840.652062565 and 2021:08:20:17:34:00:734116725. I'm using Dissect in Logstash to set the field names and assigning the data types and formats in my index mappings but am having a really hard time wrapping my head around the correct way to preserve the nanosecond precision.
For the epoch time string, I seem to be stuck between either epoch_seconds and epoch_millis, neither of which provide the required precision. For the custom format, I have the format set as "yyyy:MM:dd:HH:mm:ss:nnnnnnnnn" but can only get millisecond precision.
Can anyone point me in the right direction for this?
Thanks so much!
