[I] implement regexp_match, regexp_scalar_match and regexp_array_match for StringViewArray [arrow-rs]
Omega359 opened a new issue, #6717:
URL: https://github.com/apache/arrow-rs/issues/6717
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
We have implemented support for StringViewArray in arrow-rs (see https://github.com/apache/arrow-rs/issues/6163 and https://www.influxdata.com/blog/faster-queries-with-stringview-part-one-influxdb/ ) and to take full advantage of it, kernels that operate on strings (StringArray and LargeStringArray) need to be updated with specialized implementations that can
Natively operate on StringViewArray without having to covert first to StringArray
(Potentially) take advantage of the new string view layout
regexp_match is one of these functions that does not have native StringViewArray support yet
**Describe the solution you'd like**
1. Implement [regexp_match](https://docs.rs/arrow/latest/arrow/compute/fn.regexp_match.html) for StringViewArray
2. Implement [regexp_array_match](https://github.com/apache/arrow-rs/blob/28878d375c5bb1c2f5adb46b287e16cea768b6e7/arrow-string/src/regexp.rs#L246) for StringViewArray
3. Implement [regexp_scalar_match](https://github.com/apache/arrow-rs/blob/28878d375c5bb1c2f5adb46b287e16cea768b6e7/arrow-string/src/regexp.rs#L336) for StringViewArray
4. Tests for same
