HyukjinKwon edited a comment on issue #26875: [SPARK-30245][SQL] Add cache for Like and RLike when pattern is not static URL: https://github.com/apache/spark/pull/26875#issuecomment-574934642 @ulysses-you, I heard some concerns about this PR when the strings are very large. String.equals vs pattern complication. So, some people worry about the regressions for large strings. Do you mind if I ask to run some benchmarks for larger strings too? It would be nice if we make sure consecutive rows should have different, long strings, to gauge what kind of regression we’re going to get in a worst case.
