-
canBatch
boolean canBatch(BatchLoader.Batch other)
Returns whether another Batch can be batched to this Batch.This is possible if:
- columns list is super set of other batch's constraint columns; and
- both have same Fact Table; and
- matching columns of this and other batch has the same value; and
- non matching columns of this batch have ALL VALUES
-
hasOverlappingBitKeys
boolean hasOverlappingBitKeys(BatchLoader.Batch other)
-
hasDistinctCountMeasure
boolean hasDistinctCountMeasure()
-
hasSameCompoundPredicate
boolean hasSameCompoundPredicate(BatchLoader.Batch other)
-
haveSameStarAndAggregation
boolean haveSameStarAndAggregation(BatchLoader.Batch other)
-
haveSameClosureColumns
boolean haveSameClosureColumns(BatchLoader.Batch other)
Returns whether this batch has the same closure columns as another.Ensures that we do not group together a batch that includes a level of a parent-child closure dimension with a batch that does not. It is not safe to roll up from a parent-child closure level; due to multiple accounting, the 'all' level is less than the sum of the members of the closure level.
- Parameters:
other
- Other batch- Returns:
- Whether batches have the same closure columns
-
haveSameValues
boolean haveSameValues(BatchLoader.Batch other)
Return whether have same values for overlapping columns or has all children for others.
