The following benchmarks have been produced when investigating column store:
Before:
| Method | Mean | Error | StdDev |
|--------- |---------:|---------:|---------:|
| LeftJoin | 944.8 ms | 77.82 ms | 46.31 ms |
With column store, left join:
| Method | Mean | Error | StdDev |
|--------- |---------:|---------:|---------:|
| LeftJoin | 552.4 ms | 36.64 ms | 21.80 ms |
In this benchmark only the join code has been replaced with column store and not the normalization operator or the read operator. So the times should be possible to reduce further.
It should be investigated if changing to column store can give better performance.
Changing would be a major refactor, but it would be worth it if the performance benefits are large enough.
