Maxim Gekk created SPARK-30309: ---------------------------------- Summary: Mark `Filter` as a `sealed` class Key: SPARK-30309 URL: https://issues.apache.org/jira/browse/SPARK-30309 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.0.0 Reporter: Maxim Gekk
Add the `sealed` keyword to the `Filter` class at the `org.apache.spark.sql.sources` package. So, the compiler should output a warning if handling of a filter is missed in a datasource: {code} Warning:(154, 65) match may not be exhaustive. It would fail on the following inputs: AlwaysFalse(), AlwaysTrue() def translate(filter: sources.Filter): Option[Expression] = filter match { {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
