Data Processing at Retrieval:
•
•Simple
processing supported when retrieving files.
•Possible to request
the system to apply a Processing Plug-In on the data and to send back the result of the plug-in rather than the data
itself.
•Processing
performed on the sub-node hosting the data.
•Possible for clients to use the NGAS Cluster as a ‘number cruncher’ to
carry out parallel data
processing in a simple manner.
•Reduces the amount of
data to be transferred to the client. I.e., a floating point number may be returned rather than the entire data file.
•Can be
extended by providing new Data Processing Plug-Ins for specific contexts.
•Could be used
to integrate NGAS with the AVO or other archive services.
