For the difference between MPP and Cube preprocessing, repeat as follows:The basic idea of > MPP [1] is to increase the number of machines for parallel computing, thus increasing query speed. For example, scanning 800 million records a machine to be processed for 1 hours, but if it is handled i

When dealing with exponential market data (IDXD), I encountered a Kylin performance query problem, very strange. After some research has found the reason and successfully solved:Symptoms:Select COUNT (*) from SENSITOP.IDXD where ticker = ' 000300 ' and tradedate between ' 2016-01-01 ' and ' 2016-07-01 'Soon, less than a secondSELECT * from SENSITOP.IDXD where ticker = ' 000300 ' and tradedate between ' 2016-01-01 ' and ' 2016-07-01 'It's slow, takes m
