Is this your first time submitting a feature request?
- I have read the expectations for open source contributors
- I have searched the existing issues, and I could not find an existing issue for this feature
- I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion
Describe the feature
Support configuration of multiple semantic layer time spines at different granularities. This will enable support for sub-daily granularity while maintaining query efficiency, since we can default to the largest compatible time spine for a given query. YAML configs have been designed to look like this:
models:
- name: my_time_spine
description: "my favorite time spine"
time_spine:
standard_granularity_column: date_day # column for the standard grain of your table
custom_granularities_columns: # additional custom granularites for your timespine
- name: fiscal_year
offset: 2
- name: my_other_column
offset: 3
columns:
- name: date_day
granularity: day # set granularity at column-level for standard_granularity_column
The new fields are model.time_spine
and column.granularity
.
