Example 1 with HivePartitionDescriptor

use of org.apache.drill.exec.planner.sql.HivePartitionDescriptor in project drill by apache.

the class HivePushPartitionFilterIntoScan method getFilterOnProject.

public static final StoragePluginOptimizerRule getFilterOnProject(OptimizerRulesContext optimizerRulesContext, final String defaultPartitionValue) {
    return new PruneScanRule(RelOptHelper.some(DrillFilterRel.class, RelOptHelper.some(DrillProjectRel.class, RelOptHelper.any(DrillScanRel.class))), "HivePushPartitionFilterIntoScan:Filter_On_Project_Hive", optimizerRulesContext) {
