The three Vs of Big Data.


While talking about Big Data, we always thing about the “Big”(Volume) part. But we should also think about velocity and variety of data to get the complete picture of data.

Volume
  Size of dataset (Terabytes/Petabytes)
   Number of counting records, transactions, tables, or files.


Variety
  Structured
  Unstructured
  Semi Structured
  All of the above.

Velocity
  Batch
  Real Time
  Near Time
  Streams
