In contrast, Vertica, Greenplum, Netezza, Teradata Aster, and CitusDB are all based on PostgreSQL forks. In many cases, the client libraries behave like psql, and ease conversions at that level. As to SQL language differences, no DW platform uses "standard SQL", just as no two RDBMS use the exact same SQL dialect. I dare say database platform lock-in is a universal issue. Any migration will involve effort. |
