Storage
Storage is where data lives between ingress and consumption. It separates raw history (the bronze lake on object storage) from curated analytics tables (the gold warehouse) and holds the metadata — schemas, table catalog entries and snapshot lineage — that every other system references.
Responsibility in one sentence
Persist raw and curated datasets durably, manage partitions and snapshots, and expose authoritative schema and catalog metadata to pipelines and query engines.
