Example 16 with Float8Vector

use of org.apache.drill.exec.vector.Float8Vector in project drill by apache.

the class TestOrderedPartitionExchange method twoBitTwoExchangeRun.

/**
 * Starts two drillbits and runs a physical plan with a Mock scan, project, OrderedParititionExchange, Union Exchange,
 * and sort. The final sort is done first on the partition column, and verifies that the partitions are correct, in that
 * all rows in partition 0 should come in the sort order before any row in partition 1, etc. Also verifies that the standard
 * deviation of the size of the partitions is less than one tenth the mean size of the partitions, because we expect all
 * the partitions to be roughly equal in size.
 * @throws Exception
