Dear Sir / Madam I've searched the web but cannot find the way to use measures of Kylin, for example, with this quote from the URL of document, it seems that the measure's magic is as follows: "I write query normally to query the desired colummn and Kylin uses the index mechanism to accelerate query", can you please advise?
Count Distinct (Precise) | Welcome to Kylin 5 (apache.org) <https://kylin.apache.org/5.0/docs/modeling/model_design/measure_design/count_distinct_bitmap> Once the measure is added and the model is saved, you need to go to the Edit Aggregate Index page, add the corresponding dimensions and measures to the appropriate aggregate group according to your business scenario, and the new aggregate index will be generated after submission. You need to build index and load data to complete the precomputation of the target column. You can check the job of Build Index in the Job Monitor page. After the index is built, you can use the Count Distinct (Precise) measure to do some querying.
