wu-sheng opened a new issue #4288: Support specific linear query for new `getMultipleLinearIntValues`
URL: https://github.com/apache/skywalking/issues/4288
 
 
   In the current query protocol, you have the only option to provide the total line number. As a result, such as for percentile, you have to query P50 if you want to other metrics, such as P50->P99 or P50-P90. 
   ```
       # Query the type of metrics including multiple values, and format them as multiple linears.
       # The seq of these multiple lines base on the calculation func in OAL
       # Such as, should us this to query the result of func percentile(50,75,90,95,99) in OAL,
       # then five lines will be responsed, p50 is the first element of return value.
       getMultipleLinearIntValues(metric: MetricCondition!, numOfLinear: Int!, duration: Duration!): [IntValues!]!
   ```
   
   This new query could leverage the existing DAO feature, but filter the query result including specific linear(s) only. We could add `linearIndex` as a parameter.
   
   ```
       getMultipleLinearIntValues(metric: MetricCondition!, linearIndex: [Int!]!, duration: Duration!): [IntValues!]!
   ```
   
   I will try to work on this. If any of @apache/skywalking-committers wants to lead, please let me know.
