Rationale for this change
What changes are included in this PR?
In optimize methods for logical & physical, wrap the returned error in
DataFusionError::Context(...)
instances, where the accompanyingString
is the name of the stage/optimizer type that failed, which enables the explain to collate these failed stages to the output, instead of failing outright.For logical optimizations, this might be unnecessary since it by default failing optimizations are skipped anyway. (same with the new
logical_optimization_succeeded
field inExplain
, could just remove this)Are these changes tested?
Are there any user-facing changes?
