RedShift

RedShift is a DBMS service by Amazon - that is, one can connect to it (JDBC, ODBC), not install it. It's part of Amazon's larger AWS (Amazon Web Services) platform.

It is a massively-parallelization of what is supposedly originally PostgreSQL 8.0.2 - but apparently with some differences even in SQL coverage between the two. The parallelization uses Actian's ParAccel infrastructure (and note that Actian also offers the Vector DBMS).

Amazon already had a parallelized relational DBMS service before RedShift, RDS - but that one is not column-based.
