System catalog files

mz-debug outputs system catalog files if --dump-system-catalog is true (the default).

The generated files are in system-catalog sub-directory as *.csv files and contains:

• Core catalog object definitions
• Cluster and compute-related information
• Data freshness and frontier metric
• Source and sink metrics
• Per-replica introspection metrics (under {cluster_name}/{replica_name}/*.csv)

For more information about each relation, view the system catalog.
