Configuration
Configure Arc through arc.toml and its environment-variable overrides: storage backends, ingestion and compaction tuning, authentication, and the FIPS build variant.
Arc reads arc.toml at startup, and every key in it can be overridden by an environment variable. These pages cover what each section controls.
Overview
Every arc.toml section and the environment variable that overrides each key.
Authentication
API tokens, the first-run bootstrap token, and the validation cache.
FIPS 140-3 mode
The arc-fips build variant for regulated environments.
Storage file format
Arc's on-disk Parquet format and its compression.
