[I] MemorySourceConfig::try_swapping_with_projection discards sort information [datafusion]
srh opened a new issue, #17184:
URL: https://github.com/apache/datafusion/issues/17184
### Describe the bug
When pushing a projection down into a MemorySourceConfig, sorting information is discarded by try_swapping_with_projection. I forget what behavior this produces: it's either less efficient planning or perhaps some kind of sanity check failure during optimization. (But it is materially harmful.)
Prior to the refactor, MemoryExec had an equivalent form of this bug.
A PR is incoming.
