| 1 Parse --- a query optimizer determines optimal execution plan, parallelize query if a full scan was included in the execution plan (note the query is parallelized dynamically at execution time, automatically adapting changes in data partition and server configuration) |
| 2 Execute --- perform operations |
| 3 Fetch (Queries) --- return rows from query server processes |
| The execution and fetch phases can be performed in parallel ( pipelined parallelism) by multiple server processes |
