Re: select count(*) from table;

Thanks Nitin, Mich, if its just plain vanilla text file format, it needs to run a job to get the count so the longest of all --> Hive must be translating some operator like fetch (for count) into a map-reduce job and getting the result? Can a custom storage handler get information about the operat

Re: select count(*) from table;

If you have enabled performance optimization by enabling statistics it will come from there if the underlying file format supports infile statistics (like ORC), it will come from there if its just plain vanilla text file format, it needs to run a job to get the count so the longest of all On Tue,

select count(*) from table;

select count(*) from table; How does hive evaluate count(*) on a table? Does it return count by actually querying table, or directly return count by consulting some statistics locally. For Hive's Text format it takes few seconds while Hive's Orc format takes fraction of seconds. Regards, Amey
