I am using Redshift since two years and, as every database has its own SQL dialect and its own tricks, but it is a really good product. It is a pity that Amazon forked early PostgreSQL v8 and not PostgreSQL v9 (with array support) but if I think about databases I used before (I was admin of a Netezza instance and user of an Oracle instance, they were Data Warehouses too) I realize it is a really big step forward that now we can create with few clicks and witha really fast provisioning time, a database that took days, even month (contracts, waiting they arrive to datacenter, DBAs configuring it, installing it, etc) to have it up and running, that now thinking about Redshift or Big Query it seems to live in another era.
