Environment Variable Naming Conventions

RustFS uses a flat naming style for top-level configuration: environment variables are RUSTFS_* without nested module segments.

Examples:

RUSTFS_REGION
RUSTFS_ADDRESS
RUSTFS_VOLUMES
RUSTFS_LICENSE

Current guidance:

Prefer module-specific names only when they are not top-level product configuration.
Renamed variables must keep backward-compatible aliases until before beta.
Alias usage must emit deprecation warnings and be treated as transitional only.
Deprecated example:
- RUSTFS_ENABLE_SCANNER -> RUSTFS_SCANNER_ENABLED
- RUSTFS_ENABLE_HEAL -> RUSTFS_HEAL_ENABLED
- RUSTFS_DATA_SCANNER_START_DELAY_SECS -> RUSTFS_SCANNER_START_DELAY_SECS

Scanner environment aliases

RUSTFS_SCANNER_SPEED (canonical, also accepts MINIO_SCANNER_SPEED)
RUSTFS_SCANNER_CYCLE (canonical, also accepts MINIO_SCANNER_CYCLE)
RUSTFS_SCANNER_START_DELAY_SECS (canonical)
RUSTFS_DATA_SCANNER_START_DELAY_SECS (deprecated alias for compatibility)
RUSTFS_SCANNER_IDLE_MODE (canonical)
RUSTFS_SCANNER_CACHE_SAVE_TIMEOUT_SECS (canonical)

Drive timeout environment variables

RUSTFS_DRIVE_METADATA_TIMEOUT_SECS
RUSTFS_DRIVE_DISK_INFO_TIMEOUT_SECS
RUSTFS_DRIVE_LIST_DIR_TIMEOUT_SECS
RUSTFS_DRIVE_WALKDIR_TIMEOUT_SECS
RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS

Legacy compatibility fallback:

RUSTFS_DRIVE_MAX_TIMEOUT_DURATION This legacy variable is treated as a deprecated fallback for the operation-specific drive timeout variables above when a canonical variable is unset.
