+# Metadata Tables
Review comment:
Yes I agree that is a confusion point. So do you recommend having one
section for each engine around system tables? My current thought is to have
this page introducing the Iceberg schema, linking to related sections in each
engine page for examples of using system tables.
One of my intention to add it was because this is a very important feature
not exist in other similar products, and it provides huge benefits for users to
build data management capabilities around such information. Tables like
`manifests` and `files` also support optimizations like predicate pushdown and
file pruning, which essentially solves the big metadata issue. So I feel it's a
pity to hide such information too deeply.
