Nikhil Sheoran created SPARK-48010: -------------------------------------- Summary: Avoid repeated calls to conf.resolver in resolveExpression Key: SPARK-48010 URL: https://issues.apache.org/jira/browse/SPARK-48010 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.4.3 Reporter: Nikhil Sheoran
Consider a view with a large number of columns (~1000s). When resolving this view, looking at the flamegraph, observed repeated initializations of `conf` to obtain the `resolver` for each column of the view. This can be easily optimized to reuse the same resolver (obtained once) for the various calls to `innerResolve` in `resolveExpression`. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
