Hi dear drill devloper, Now we are deploy the 0.7 version drill for
statistics analysis. I found that the parquet file store the column summary
info in pageheader (like min,max,count and so on), but in the datareader these
info seems not to be used for pre-filtering files. For example, when I search
the records that attribute_A = 10, if the column's (min,max) =(1,9) , skip to
scan the data seems the best choice. I want to check if drill will do this
operation in analysis process.btw：In TableStatsCalculator.getRegionSizeInBytes
method, if avgRowSizeInBytes is to large, the return value will be out of int
range. So the code should be fixed like "return
((long)avgRowSizeInBytes)*1024L*1024L".
Thanks&Regards
