Sources in packages - considerations and ideas

[drewbanin]

• If a project source overrides a package source, does dbt source snapshot-freshness run two sets of freshness checks?
• Consider adding a third arg to the source function that specifies a package to search in. If two dependency packages provide the same source, this arg is required to make the source method call unambiguous -- raise an error.
• Figure out how we can render sensible docs in this environment

Let's consider #2:

Consider adding a third arg to the source function that specifies a package to search in. If two dependency packages provide the same source, this arg is required to make the source method call unambiguous -- raise an error.

Can we make source overriding/replacement explicit? Drew and Jake to discuss
