Dataset Read/Write

Hi All,

If a dataset is created using a 2 node config file, then should it always be read by a 2 node config file ideally?. If needed to be read by > 2 node config file (3 or more), then is there a workaround?

Your inputs are greatly appreciated,
Whale.

You can always read it with a higher configuration - just make sure that the configuration includes the same nodes that created the DataSets.

The point here is that a data file (containing the actual data that is loaded in the DataSet) is created on each node defined in the configuration file used to create the DataSet. When reading the DataSet - all the data files for that DataSet should be accessible to the Configuration used to read.

... which means that all the nodes named in the configuration file with which it was created must be accessible under the new configuration file's regime. The control file (blah.ds) contains the locations of the data files, though not readily in human-readable format.
