betodealmeida commented on issue #8226: Handle int64 columns with missing data in SQL Lab URL: https://github.com/apache/incubator-superset/pull/8226#issuecomment-532080546 > The dataframe implementation looks good, as does the Presto engine dtype fix, but does this fully address #8225 if only Presto is handled? Are there other databases this fix should be implemented for (even in a separate PR)? You're right, this only fixes Presto. I'll do a separate PR addressing the other DBs. > Also curious about your thoughts on the feasibility of the PyArrow workaround here. Looks like it would solve our problem, but I don't know if it would be better to monkey patch PyArrow (or if it can be done), or if we should create a light wrapper around it.
