# <summary of what this cache is>
# Cache keys: The 64 to 128 bit string key of the Value.get64BitHash of the expression and the valid bindings
#             for it, plust one character of "T" or "F" to represent if expression is variable definition. We
#             do not keep the full key since collisions are unlikely and would unnecessarily burden the cache,
#             especially for large expressions, the size of which can be large compared to the small data we
#             are storing.
# Cache values: List<DesignGuidanceExpression> of expression guidance for the given expression, bindings and
#               whether it's variable definition

# 2 ~30 character strings + 1 10 character string + 4 integers = 1248 bytes * 10 per list on average * 500 lists + 500 128 bit cache keys ~= 6 MB

# Background memory shrinkage (active eviction) [When MemoryShrinker is enabled, determine how often the thread should be triggered to shrink the cache and what the maxIdle time is for an element]
# Run shrinker every hour. Entries are generally valid for a designer's editing session and then once they get
# replicated via the IAReplicator. This generally happens within a minute of object save.
