### Is your feature request related to a problem or challenge? The kernels in `arrow-string/src/like.rs` reject `RunEndEncoded` arrays: ``` Invalid string/binary operation: RunEndEncoded(non-null Int32, Utf8) LIKE Utf8 ``` Callers have to decode first, which materializes every row and matches each value once per row instead of once per run. ### Describe the solution you'd like Accept run-end encoded operands, including run-end encoded dictionaries, in `like`, `ilike`, `nlike`, `nilike`, `starts_with`, `ends_with`, `contains` and `eq_ignore_ascii_case`. Against a scalar, match each run once and repeat the result across the run. ### Describe alternatives you've considered Decoding before matching, which is what callers do today. ### Additional context Related to #3520. -- This is an automated message from the Apache Git Service.
