# Maximum number of cached objects at any given time
#
# Approximate max source table URN length: 200 (1 byte per char)
# Approximate extreme for SourceFields per entry: 50 (8 bytes per long)
#
# Key: 200 bytes
# Value: Each source field contains a name, type (string), 2 booleans, a long and a list of longs
# representing interchangeable AppianType ids
# Assuming name is no longer than 32 characters, type is no longer than 20 characters, and there are
# no more than 5 interchangeable AppianTypes, this means the max bytes per SourceField would be
# 32 + 20 + (2*1) + 8 + (8*5) = 102 bytes per SourceField
# Assuming no more than 50 SourceFields per table, the max bytes per entry would be
# 200 + (50*102) = 5300 bytes = 5.3 KB
# Reasoning: Each entry takes ~ 5 KB (extreme), so 400 entries would be less than 2 MB of memory.
