BatchedRunningWindowBinaryFixer

class BatchedRunningWindowBinaryFixer extends BatchedRunningWindowFixer with Logging

This class fixes up batched running windows by performing a binary op on the previous value and those in the the same partition by key group. It does not deal with nulls, so it works for things like row_number and count, that cannot produce nulls, or for NULL_MIN and NULL_MAX that do the right thing when they see a null.

  12. def fixUp(samePartitionMask: Either[ColumnVector, Boolean], sameOrderMask: Option[Either[ColumnVector, Boolean]], windowedColumnOutput: ColumnView): ColumnVector

    Fix up windowedColumnOutput with any stored state from previous batches.

    Fix up windowedColumnOutput with any stored state from previous batches. Like all window operations the input data will have been sorted by the partition by columns and the order by columns.

    samePartitionMask

    a mask that uses true to indicate the row is for the same partition by keys that was the last row in the previous batch or false to indicate it is not. If this is known to be all true or all false values a single boolean is used. If it can change for different rows than a column vector is provided. Only values that are for the same partition by keys should be modified. Because the input data is sorted by the partition by columns the boolean values will be grouped together.

    sameOrderMask

    a mask just like samePartitionMask but for ordering. This happens for some operations like rank and dense_rank that use the ordering columns in a row based query. This is not needed for all fixers and is not free to calculate, so you must set needsOrderMask to true if you are going to use it.

    windowedColumnOutput

    the output of the windowAggregation without anything fixed/modified. This should not be closed by fixUp as it will be handled by the framework.

    returns

    a fixed ColumnVector that was with outputs updated for items that were in the same group by key as the last row in the previous batch.
