In Big Data analytics systems, there may be many repeated query sqls. Doris generates a query plan for each sql，and call BE and return the query result。These repeated query sqls costs many resources,but return same results. Therefore, Doris can add a cache system to save the query SQL and the result of the SQL statement. If analytics system call the same query next time , the query result is directly returned from the cache to avoid excessive doris query consumption. After a database is deleted, a table is deleted, the table schema is changed, or loaded new data to a table, the corresponding query cache becomes invalid. This feature greatly enhance the query speed in scenarios where there are may repeated queries. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
