Description

Add guardrails for the number of items and size of collections. For example:

# Guardrail to warn or fail when encountering larger size of collection data than threshold.
# The two thresholds default to 0KiB to disable.
collection_size_warn_threshold: 0KiB
collection_size_fail_threshold: 0KiB

# Guardrail to warn or fail when encountering more elements in collection than threshold.
# The two thresholds default to -1 to disable.
items_per_collection_warn_threshold: -1
items_per_collection_fail_threshold: -1
