Configuration
Configure Arc Enterprise: the arc.toml key reference, the two cluster deployment patterns, clustering and failover settings, and edge sync against a clustered hub.
Arc Enterprise is configured through arc.toml, with environment variables overriding any key. The Enterprise-only sections are [license], [cluster], [tiered_storage], [audit_log], [governance], and [query_management].
Read Deployment patterns before anything else. The choice between shared object storage and local disks with peer replication determines most of the other settings on this page, and it is expensive to reverse once a cluster holds data.
Deployment patterns
Shared object storage or local disks with peer replication, and what each costs you operationally.
Configuration overview
Every arc.toml section and its environment-variable equivalent, including the licensed features.
Clustering
Node roles, seeds, Raft, peer file replication, and automatic writer failover.
Edge sync with a clustered hub
What changes when the hub receiving edge Parquet files is a cluster rather than a single node.
