[I] perf: Optimize some functions to rewrite dictionary-encoded strings [datafusion-comet]
andygrove opened a new issue, #504:
URL: https://github.com/apache/datafusion-comet/issues/504
### What is the problem the feature request solves?
We have some functions that unpack dictionary-encoded strings and then perform a transformation on the unpacked array, but it would be better to transform the dictionary instead. We should optimize these functions to do that.
The functions include:
- hex
- cast string to other types
There may be others.
### Describe the potential solution
