For 2) I think running presto on EMR is able to let you run read-optimized queries. I don't quite understand how exactly Athena not support Hudi as it is Presto underlying. Perhaps @Udit could give some insights from AWS?
As @Raghvendra you mentioned, another option is to export Hudi dataset to plain parquet files for Athena to query on RFC-9 is for this usecase https://cwiki.apache.org/confluence/display/HUDI/RFC+-+09+%3A+Hudi+Dataset+Snapshot+Exporter The task is inactive now. Feel free to pick up if this is something you'd like to work on. I'd be happy to help with that.
