> Hi, I think the selfsame OLAP querys in prod env is very rare. Do you test this PR in your prod env? what's the cache hit rate? The Apache Kylin use SQL result cache Like this PR, After Kylin run many years in MEITUAN, we could confirm the SQL result cache is meaningless for OLAP system. 3ks the result cache has been used in Jingdong for more than half a year, and the cache hit rate is also very high, especially in the e-commerce industry like ours, in special periods and business scenarios, its hit rate is very high As far as I know, most of the business of meituan is near real-time, and the scope of business use and analysis is slightly different from ours. So maybe the hit rate of cache is not high ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
