Last time I looked at Presto, it works fine for simple queries (e.g. scanning data and aggregating it into a small result set) but the performance was prone to falling off a cliff as queries got moderately complex - it comes up with a bad query plan or query execution OOMs when data doesn't fit in memory.
Hive and other SQL-on-Hadoop systems tend to do better in that department.
