sql server - ColumnStore Index vs Columnar DB -


there option called "columnstore index" available in sql server 2012.
comparable columnar databases such cassandra, hbase?
few advantages of going sql server 2012 can be:

  • it updateable
  • it relational

what other factors can considered choose between sql server 2012 , other columnar databases in case faster query performance requirement.

i'm not sure mean "it updatable", in sql server 2012 tables have columnstore index cannot updated. must first drop columnstore index or must partition around columnstore index in order support changes underlying data.

also, columnstore indexes useful in dw systems large amounts of data have aggregated , accessed quickly.

in sql server 2012 have alternative of indexed (materialized) views.
