  • Method Details

    • getDdlList

      List<String> getDdlList()
       Optional. DDL statements to add new indexes that will improve the query.
      repeated string ddl = 1 [(.google.api.field_behavior) = OPTIONAL];
      Returns:
      A list containing the ddl.

    • getDdlCount

      int getDdlCount()
       Optional. DDL statements to add new indexes that will improve the query.
      repeated string ddl = 1 [(.google.api.field_behavior) = OPTIONAL];
      Returns:
      The count of ddl.

    • getDdl

      String getDdl(int index)
       Optional. DDL statements to add new indexes that will improve the query.
      repeated string ddl = 1 [(.google.api.field_behavior) = OPTIONAL];
      Parameters:
      index - The index of the element to return.
      Returns:
      The ddl at the given index.

    • getDdlBytes

      com.google.protobuf.ByteString getDdlBytes(int index)
       Optional. DDL statements to add new indexes that will improve the query.
      repeated string ddl = 1 [(.google.api.field_behavior) = OPTIONAL];
      Parameters:
      index - The index of the value to return.
      Returns:
      The bytes of the ddl at the given index.

    • getImprovementFactor

      double getImprovementFactor()
       Optional. Estimated latency improvement factor. For example if the query
 currently takes 500 ms to run and the estimated latency with new indexes
 is 100 ms this field will be 5.
      double improvement_factor = 2 [(.google.api.field_behavior) = OPTIONAL];
      Returns:
      The improvementFactor.
