Add aggregate groups

  • PUT http://host:port/kylin/api/index_plans/agg_groups

  • Introduced in: 5.0

  • HTTP Header

    • Accept: application/vnd.apache.kylin-v4-public+json
    • Accept-Language: en
    • Content-Type: application/json;charset=utf-8
  • HTTP Body: JSON Object

    • project - required string, project name
    • model - required string, model name
    • aggregation_groups - required JSON Object[], agg group json array, can add multiple agg groups
      • dimensions - required array[string], dimension array, must be in database.table format, and the added dimension must have been added as a dimension in the model
      • measures - optional array[string], measure array, the added measure name is the measure name defined in the model, case-sensitive
      • mandatory_dims - optional array[string], mandatory dimension array, the dimensions that must be included in the index generated by the aggregate group
      • hierarchy_dims - optional array[array[string]], hierarchy dimension array, the dimensions that can be optimized according to the hierarchical relationship in the index generated by the aggregate group, a set of hierarchy dimensions in an array
      • joint_dims - optional array[array[string]], joint dimension array, the dimensions that must also be included in the index generated by the aggregate group, a set of joint dimensions in an array

      NOTICEmandatory_dimshierarchy_dimsjoint_dims must be in dimensions, and any dimension can only be set once in mandatory dimension, hierarchy dimension or joint dimension.

      • dim_cap - optional int, Maximum number of dimension combinations(MDC) for a single aggregate group, positive integer
    • global_dim_cap - optional int, global MDC in this request, priority global_dim_cap < dim_cap
    • restore_deleted_index - optional boolean, When the indexes generated by the aggregate group have been deleted, whether to generate these indexes again when adding the aggregate group, the default is false, which means not to add.
