class RuleExtension extends (SparkSessionExtensions) ⇒ Unit with Logging

Injects the DataSkippingFileIndexRule into catalyst as part of the operatorOptimization rules and enable it using spark session extensions injectOptimizerRule.

To use with regular spark session (either pyspark or scala): val spark = SparkSession .builder() .appName("Xskipper") .config("spark.master", "local[*]") // comment out to run in production .config("spark.sql.extensions", "io.xskipper.RuleExtension") //.enableHiveSupport() .getOrCreate()

To use with thrift server: 1) get a Xskipper jar file 2) start the thrift server, with the extension: start-thriftserver.sh --jars <XskipperJar> --conf spark.sql.extensions=io.xskipper.RuleExtension 3) you can now connect via JDBC (e.g. - beeline/squirrel/ any other JDBC driver)
