Enum datafusion::logical_plan::plan::Partitioning
source · [−]Expand description
Logical partitioning schemes supported by the repartition operator.
Variants
RoundRobinBatch(usize)
Allocate batches using a round-robin algorithm and the specified number of partitions
Hash(Vec<Expr>, usize)
Allocate rows based on a hash of one of more expressions and the specified number of partitions. This partitioning scheme is not yet fully supported. See https://issues.apache.org/jira/browse/ARROW-11011
