Data Process.


It merges the measures of n input datacubes with the same fragmentation structure and creates a new datacube with the union of the n measures. NOTE: only single measure data cubes can be merged and a new implicit dimension will be created.


  • cubes: name of the datacubes to merge. The names must be in PID format. Multiple-value field: list of cubes separated by “|” can be provided.
  • schedule: scheduling algorithm. The only possible value is 0, for a static linear block distribution of resources.
  • container: name of the container to be used to store the output cube; by default, it is the input container.
  • dim: name of the new dimension to be created; by default a unique random name is chosen.
  • dim_type: data type of the new dimension. Default value is “long”.
  • number: number of replies of the first cube; by default the first cube is considered only once.
  • description: additional description to be associated with the output cube.

System parameters

  • exec_mode: operator execution mode. Possible values are async (default) for asynchronous mode, sync for synchronous mode with json-compliant output.
  • ncores: number of parallel processes to be used (min. 1).
  • sessionid: session identifier used server-side to manage sessions and jobs. Usually, users don’t need to use/modify it, except when it is necessary to create a new session or switch to another one.
  • objkey_filter: filter on the output of the operator written to file (default=all => no filter, none => no output, mergecubes => shows operator’s output PID as text).


Merge the datacubes identified by the PIDs “URL/1/1” and “URL/1/2”:
