@larkee larkee commented Oct 13, 2020

This PR fixes a bug in the StreamedResultSet logic for merging chunked values where the chunked value is an array of structs and the chunk boundary splits a struct element in two and the halves aren't correctly merged.

This bug results in the struct element incorrectly being split into two partial struct elements.


('foo', 0.5, DatetimeWithNanoseconds(2020, 1, 1, 0, 0, tzinfo=<UTC>))


('foo', 0.5)

This bug is caused by an unhandled Unmergable error in _merge_struct. This PR adds the same handling used for _merge_array and a unit test to prove the fix works.
