URL: https://github.com/apache/datafusion/issues/18071
Currently, we use the `enable_dynamic_filter_pushdown` config to control
topk and join dynamic filter iiuc.
I think it'll be better to give users more flexibility to choose which
dynamic filter. Such as, they may only need topk dynamic filter, or there are
some bugs in join dynamic filter.
Proposal:
1. Add two new configuration options to replace the single
`enable_dynamic_filter_pushdown`:
- `enable_topk_dynamic_filter_pushdown` - for TopKdynamic filters
- `enable_join_dynamic_filter_pushdown` - for Join dynamic filters
2. Keep the old config for backward compatibility, make it control both new
configs.
