Columnar: parallel query #4669

Open jeff-davis opened 3 years ago

jeff-davis commented 3 years ago

Allow columnar to make use of parallel query, so that different backends read different stripes.

Any update on that. We are currently evaluating columnar tables and citus and compared to other solutions, columnar queries are really slow (10x slower that sql server express clustered columnstore index and 8x slower than MariaDb CS)
