That sounds like a great idea! Adding support for the selector when using LoadMode.DBT_MANIFEST
and LoadMode.CUSTOM
would definitely enhance the functionality of Cosmos for dbt users. It's clear that you've put a lot of thought into the potential solution and the complexities involved in parsing the full YAML selector. Your proposed solution of adding a new method to GraphSelector
for parsing the full YAML selector seems like a step in the right direction. Your understanding of the challenges and the reasoning behind using selectors over simple selection options is commendable. I encourage you to go ahead and create a PR with your proposed solution. Your contribution will be valuable to the Cosmos community. Keep up the great work!

This is a follow up to #718 for which support for using selector was added in #755 for dbt ls load mode. It would be great if we could add support for the selector when using
LodeMode.DBT_MANIFEST
andLoadMode.CUSTOM
.Adding support for manifest/custom will involve first parsing the YAML selectors which can have 3 types of
definition
for the selector:full yaml with method selection:
The selector can also have
union
,intersection
andexclude
like in the example below:Further more there can be selector inheritancewhere one selector can reference another one.
The full yaml parsing will be the most challenging, but this is the reason why selectors are often used over
--select
and--exclude
for complex selections.One possible solution is to add a new method to
GraphSelector
which can parse the full YAML selector, there is a method currently for parsing REGEX strings.
