And the key here is the word "UTCFILETIME". @Gatsby-Lee : I guess athena added support for real time query in one of the latest versions. privacy statement. I know that the actual execution time is '2017-04-27-11.45.03' Amazon Athena is based on Presto, so you can use Date and Time Functions and Operators Presto. ( in this case, it's the managed Presto ) It is not a Hudi fault, so we need to wait for athena, but I think it should not be solved soon in Hudi side is there anything what we can do? Although I can see timestamp type, the type I see through AWS Athena was bigint. I have tried: from_unixtime (timestamp DIV 1000) AS readableDate And '19700101').
