Weird execution time for a query
Hi ,
I have a table with 10 columns 7 numeric and 3 chars , it include 6m records , reading all table data take about 50secounds , i run a profile on top of simple select * from the table and seems like the most query time was spend of the Root stage .
My understanding is that probably most of the time that was spend he is for the uncompressed of the data (See attach execution , i add execution time + clock time on it ) , seeing the high clock time lead to the understanding that it spend the time on the uncompressed stage
Please advise .
