vladimirg-db opened a new pull request, #46365: URL: https://github.com/apache/spark/pull/46365
### What changes were proposed in this pull request? Error message template regex is now precompiled to avoid unnecessary work ### Why are the changes needed? `SparkRuntimeException` uses `SparkThrowableHelper`, which uses `ErrorClassesJsonReader` to create error message string from templates in `error-conditions.json`, but template regex is compiled on every `SparkRuntimeException` constructor invocation. This slows down error construction, in particular `UnivocityParser` + `FailureSafeParser`, where it's a hot path. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? `testOnly org.apache.spark.sql.errors.QueryExecutionErrorsSuite` ### Was this patch authored or co-authored using generative AI tooling?
