Cassandra database presentation
This BDMS enables users to work with large amount of data, and ONE DATA gives the user the possibility to load data from a specific table inside a predefined Key-Space.
This processor does not need Dataset from a preceding processor (i.e: it does not have any input node)
The Processor interface looks as follows:
WARNING: table and Key-Space must NOT be blank and must NOT contain any white space
The output of this processor is the Data from the table of interest with the defined preprocessing (if provided within the third field)
The "Query" field can be used to process the data of interest.
For example Grouping, Counting, Sorting or filtering and in general it supports SQL queries which gives the user more control over the result data.
After searching for the Dataset in the given Key-Space and applying the specified preprocessing, this processor will generate the Dataset which can be used by other processors
NOTE THAT: This processor works on certain specific instances
