# This property controls how to handle the projection of nested levels of the same hierarchy.
# Specifically the use of the technique involving nested level decoration rules.
# In that case the planner queries only the lowest level members, later the post-processing queries the outer levels if required.

# - never: never use this technique
# - automatic: allow the planner to decide whether to use or not this technique.

# This property tells whether the provider may filter the data before applying the MDX.
# It may take one of this values:

# - forNonEmpty: Only in the presence of MDX edge NON EMPTY the provider filters the data before applying the MDX.

# For LOLAP providers to decide if producing MDX that selects individual members
# on an axis is worthwhile (vs. using a "dim/hier.MEMBERS" clause in the MDX produced
# to retrieve measure values).
# maxAxisSelectionsIgnoreRatio is a hard upper bound on the number of individual members 
# that can be selected. If it is set to -1, there is no upper bound.
# The heuristic is as follows:
# if (maxAxisSelectionsIgnoreRatio > -1 && selCount > maxAxisSelectionsIgnoreRatio ||
#		(selCount > maxAxisSelections && selCount > dim.getCardinality() * maxAxisSelectionsRatio))
# 		// Use a "dim/hier.MEMBERS" clause in the MDX produced.

# 
# For LOLAP providers to decide if splitting a symmetric query for a requested set of tuples into
# multiple more precise queries is worthwhile.
# The heuristic for determining whether to split a requested set into multiple queries is:
# if (symmetricTuples - requiredTuples > minExcessTuplesForSplitQuery 
#		&& symmetricTuples / requiredTuples > excessTuplesRatioForSplitQuery)
# When either threshold is set to -1, a requested set of tuples is never split into multiple queries.
