I want to move data from a SQL server database to Hbase / Cassandra etc. How to decide which bigdata database to use?

Do I need to develop a plan for moving data from an SQL server database to any of the bigdata databases? Some of the questions I was thinking about are the following:

  • How big is the data?
  • What is the expected growth rate for this data?
  • What queries will be executed frequently? for example: search, range scan, full scan, etc.
  • How often do data move from source to destination?

Can someone help add to this profile?
