  2. Detailed Documentation

Function: PrepareMetricQueryDeltaTable​

  • Purpose: This function constructs a query to fetch metrics, applying time and space aggregations. It determines whether to use an optimized query path based on the input mq and prepares the query accordingly.
  • Parameters:
    • start (int64): The start timestamp for the query.
    • end (int64): The end timestamp for the query.
    • step (int64): The step interval for the query.
    • mq (*v3.BuilderQuery): A pointer to the query builder object, containing details about the query, such as group by, order by, space aggregation, and filters.
  • Returns:
    • (string): The constructed SQL query string.
    • (error): An error object, if any error occurred during query preparation.
