tdas opened a new pull request #27326: [SPARK-30609] Allow default merge command resolution to be bypassed by DSv2 sources URL: https://github.com/apache/spark/pull/27326 ### What changes were proposed in this pull request? Skip resolving the merge expressions if the target is a DSv2 table with ACCEPT_ANY_SCHEMA capability. ### Why are the changes needed? Some DSv2 sources may want to customize the merge resolution logic. For example, a table that can accept any schema (TableCapability.ACCEPT_ANY_SCHEMA) may want to allow certain merge queries that are blocked (that is, throws AnalysisError) by the default resolution logic. So there should be a way to completely bypass the merge resolution logic in the Analyzer. ### Does this PR introduce any user-facing change? No, since merge itself is an unreleased feature ### How was this patch tested? added unit test to specifically test the skipping.
