Instead of outputting the type as TIMESTAMP, Presto now outputs it as TIMESTAMP(3). Unfortunately, with Panda's DataFrame my timestamp columns are dtyped as object instead of datetime now. Any known workaround? Would newer versions fix this? Thanks, James -------------- next part -------------- An HTML attachment was scrubbed...
