Hey @lostluck
I just started a test run with your changes applied with the bigtable io connector (#23411).
Unfortunately I still ran into the following error:
reflect.Set: value of type struct { RowKey string; Ops []struct { Family string; Column string; Ts int64; Value []uint8 }; GroupKey string } is not assignable to type bigtableio.Mutation.I played around with this implementation but wasn't able to make it work. My knowledge on the reflect package is somehow limited though.
