Detailed Description

A helper class to represent a Kudu range partition with a custom hash bucket schema. The hash sub-partitioning for a range partition might be different from the default table-wide hash bucket schema specified during the creation of a table (see KuduTableCreator::add_hash_partitions()). Correspondingly, this class provides a means to specify a custom hash bucket structure for the data in a range partition.

Constructor & Destructor Documentation

◆ KuduRangePartition()

kudu::client::KuduRangePartition::KuduRangePartition	(	KuduPartialRow *	lower_bound,
		KuduPartialRow *	upper_bound,
		KuduTableCreator::RangePartitionBound	lower_bound_type = KuduTableCreator::INCLUSIVE_BOUND,
		KuduTableCreator::RangePartitionBound	upper_bound_type = KuduTableCreator::EXCLUSIVE_BOUND )

Create an object representing the range defined by the given parameters.

Parameters

[in]	lower_bound	The lower bound for the range. The KuduRangePartition object takes ownership of the parameter.
[in]	upper_bound	The upper bound for the range. The KuduRangePartition object takes ownership of the parameter.
[in]	lower_bound_type	The type of the lower_bound: inclusive or exclusive; inclusive if the parameter is omitted.
[in]	upper_bound_type	The type of the upper_bound: inclusive or exclusive; exclusive if the parameter is omitted.

◆ add_hash_partitions()

Status kudu::client::KuduRangePartition::add_hash_partitions	(	const std::vector< std::string > &	columns,
		int32_t	num_buckets,
		int32_t	seed = 0 )

Add a level of hash sub-partitioning for this range partition.

The hash schema for the range partition is defined by the whole set of its hash sub-partitioning levels. A range partition can have multiple levels of hash sub-partitioning: this method can be called multiple times to define a multi-dimensional hash bucketing structure for the range. Alternatively, a range partition can have zero levels of hash sub-partitioning: simply don't call this method on a newly created KuduRangePartition object to have no hash sub-partitioning for the range represented by the object.
