Does anyone know if there is a way to filter on time fields (either defined as Dimension Groups or Dimensions under the hood in LookML) such that you can specify a microseconds value?
My data is structured such that it’s critical to be able to apply microsecond-level precision when filtering, such that I can respect the differences between values like 2014-09-03 23:59:59.999999 and 2014-09-03 23:59:59.012347 and treat them differently.
So far, no matter what I’ve tried, I’ve only been able to specify second-level precision when filtering:
- I’ve tried regular filtering using the
before and on or after options - I’ve tried the
matches (advanced) also using the before and after options - I’ve tried a custom filter, but
date_time/6 truncates the seconds value to an integer - I’ve created a separate Dimension for the field I want to be able to filter at microsecond-level precision, and tried to filter on it
This Available Time-Based Types doc made me think that creating a separate Dimension with the type: date_microsecond parameter might cause the filtering to allow microsecond-level precision, but that was not the case.
For what it’s worth, at this point I’ve been trying to avoid introducing a templated filter/parameter to handle adding in the microsecond-level precision, but perhaps that is the only way to do so...
