Support StringView for binary operators like `~`, `!~`, etc

[alamb]

Is your feature request related to a problem or challenge?

Part of #11752

As we work to complete StringView support in DataFusion @2010YOUY01 noticed on #11752 (comment) that we don't currently support Regexp like binary operators https://datafusion.apache.org/user-guide/sql/operators.html#op-re-match for string view

Reproducer

CREATE TABLE t0(v0 DOUBLE, v1 DOUBLE, v2 BOOLEAN, v3 BOOLEAN, v4 BOOLEAN, v5 STRING);
INSERT INTO t0(v1, v5, v2) VALUES (0.7183242196192607, 'Tn', true);
CREATE TABLE t0_stringview AS SELECT v0, v1, v2, v3, v4, arrow_cast(v5, 'Utf8View') as v5 FROM t0;

> select v5 ~ 'foo' from t0_stringview;
Internal error: Data type Utf8View not supported for binary_string_array_flag_op_scalar operation 'regexp_is_match' on string array.
This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker

> select regexp_match(v5, 'foo') from t0_stringview;
+--------------------------------------------+

Describe the solution you'd like

StringView should be supported for these operators (aka the query should run without error)

Describe alternatives you've considered

Here are the relevant operator names:

            | Operator::RegexMatch
            | Operator::RegexIMatch
            | Operator::RegexNotMatch
            | Operator::RegexNotIMatch
            | Operator::LikeMatch
            | Operator::ILikeMatch
            | Operator::NotLikeMatch
            | Operator::NotILikeMatch

Here is the dispatch code:

datafusion/datafusion/physical-expr/src/expressions/binary.rs

Lines 621 to 632 in 0f96af5

	RegexMatch => {
	binary_string_array_flag_op!(left, right, regexp_is_match, false, false)
	}
	RegexIMatch => {
	binary_string_array_flag_op!(left, right, regexp_is_match, false, true)
	}
	RegexNotMatch => {
	binary_string_array_flag_op!(left, right, regexp_is_match, true, false)
	}
	RegexNotIMatch => {
	binary_string_array_flag_op!(left, right, regexp_is_match, true, true)
	}

It appears that the corresponding arrow-rs kernel does not yet have support for StringView
https://docs.rs/arrow-string/52.2.0/src/arrow_string/regexp.rs.html#307-311

So what I would suggest is:

1. Implement a PR in datafusion with coercion from Utf8View --> Utf8 (aka cast arguments back to string)
2. File an upstream ticket in arrow-rs for supporting string view with the regexp_like kernels and leave a link to that ticket in the datafusion code

Additional context

Looks like #12168 also might be a starting point to solve this problem. I also think about solution 2 when handling that PR, and IMO solution 2 is the better option. I will take this one.

I agree solution 2 is better -- it just will take longer as it needs two coordinated PRs. One thing we have done in the past is do the initial implementation in DataFusion, and then file a ticket / port the code upstream to arrow-rs. Once the code is release in arrow-rs and available in Datafusion we remove the copy in DataFusion

I think this ticket is done now (though there is some follow up work to improve performance / port the code upstream)

Thanks again @tlm365
