vladimirg-db opened a new pull request, #46400: URL: https://github.com/apache/spark/pull/46400
# What changes were proposed in this pull request? New lightweight exception for control-flow between UnivocityParser and FalureSafeParser to speed-up malformed CSV parsing ### Why are the changes needed? Parsing in `PermissiveMode` is slow due to heavy exception construction (stacktrace filling + string template substitution in `SparkRuntimeException`) ### Does this PR introduce _any_ user-facing change? No, since `FailureSafeParser` unwraps `BadRecordException` and correctly rethrows exceptions in `FailFastMode` ### How was this patch tested? - `testOnly org.apache.spark.sql.catalyst.csv.UnivocityParserSuite` - Manually run csv benchmark on DB benchmark workspace - Manually checked correct and malformed csv in sherk-shell (org.apache.spark.SparkException is thrown with the stacktrace) ### Was this patch authored or co-authored using generative AI tooling?
