OPH_CUBESIZE

Description

Type

Metadata Access.

Behaviour

It computes and displays the size of the input datacube.

Parameters

  • cube: name of the input datacube. The name must be in PID format.
  • schedule: scheduling algorithm. The only possible value is 0, for a static linear block distribution of resources.
  • byte_unit: measure unit used to show datacube size. The unit can be KB, MB (default), GB, TB or PB.

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, cubesize => shows cube size).

Examples

Compute the size of the datacube “URL/1/1”:

[OPH_TERM] >>  oph_cubesize cube=URL/1/1;
