- def pruneColumns(scanBuilder: ScanBuilder, relation: DataSourceV2Relation, projects: Seq[NamedExpression], filters: Seq[Expression]): (Scan, Seq[AttributeReference])
Applies column pruning to the data source, w.r.t.
Applies column pruning to the data source, w.r.t. the references of the given expressions.
- returns
the
Scaninstance (since column pruning is the last step of operator pushdown), and new output attributes after column pruning.
- def pushFilters(scanBuilder: ScanBuilder, filters: Seq[Expression]): (Either[Seq[Filter], Seq[Predicate]], Seq[Expression])
Pushes down filters to the data source reader
Pushes down filters to the data source reader
- returns
pushed filter and post-scan filters.
- def pushLimit(scanBuilder: ScanBuilder, limit: Int): Boolean
Pushes down LIMIT to the data source Scan.
Pushes down LIMIT to the data source Scan.
- returns
the tuple of Boolean. The first Boolean value represents whether to push down, and the second Boolean value represents whether to push down partially, which means Spark will keep the Limit and do it again.
- def pushTableSample(scanBuilder: ScanBuilder, sample: TableSampleInfo): Boolean
Pushes down TableSample to the data source Scan
- def pushTopN(scanBuilder: ScanBuilder, order: Array[SortOrder], limit: Int): (Boolean, Boolean)
Pushes down top N to the data source Scan.
Pushes down top N to the data source Scan.
- returns
the tuple of Boolean. The first Boolean value represents whether to push down, and the second Boolean value represents whether to push down partially, which means Spark will keep the Sort and Limit and do it again.
