  1. Overview This file contains functions for building ClickHouse queries for cumulative metrics to be displayed in a table format. It implements logic to handle cumulative metrics and calculates the rate of change over time.

  2. Detailed Documentation

stepForTableCumulative(start, end int64) int64​

  • Purpose: Calculates an appropriate step size for querying cumulative metrics for table display.
  • Parameters:
    • start (int64): The start timestamp in milliseconds.
    • end (int64): The end timestamp in milliseconds.
  • Returns: An integer representing the calculated step size in seconds.

buildMetricQueryForTable(start, end, _ int64, mq *v3.BuilderQuery) (string, error)​

  • Purpose: Builds a ClickHouse query for cumulative metrics to be displayed in a table format based on the provided parameters.
  • Parameters:
    • start (int64): The start timestamp in milliseconds.
    • end (int64): The end timestamp in milliseconds.
    • _ (int64): Unused parameter.
