Description
Type
Data Process.
Behaviour
It performs a roll-up operation on a datacube, i.e. it transforms dimensions from explicit to implicit.
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.
- ndim: number of explicit dimensions that will be transformed in implicit dimensions. Default value is ‘1’.
- container: name of the container to be used to store the output cube; by default, it is the input container.
- 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).
- nthreads: number of parallel threads per process 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, rollup => shows operator’s output PID as text).
Examples
Do a roll-up on datacube identified by the PID “URL/1/1” on 1 explicit dimension:
[OPH_TERM] >> oph_rollup cube=URL/1/1;
