Struct LocalFsArchive 

pub struct LocalFsArchive { /* private fields */ }

Local-filesystem archive. Copies events to <root>/<tenant>/<yyyy-mm>/archive-<from>-<to>.parquet using the same atomic-write primitive as live storage.

Best fit: a separate, cheaper, possibly larger volume than the hot path uses. NOT a replacement for off-site backup — same datacenter failure modes apply. For multi-region durability, use an object-store backend.

Implementations

impl LocalFsArchive

pub fn new(root: impl Into<PathBuf>) -> Result<Self>

Create a new local-filesystem archive rooted at root. The directory is created if it doesn’t exist. Returns Err if the path is unusable (no permissions, points at a file, etc).

pub fn root(&self) -> &Path

Path to the archive root (for tests and logging).

Trait Implementations

impl ArchiveTarget for LocalFsArchive

fn archive( &self, tenant_id: &str, from: DateTime<Utc>, to: DateTime<Utc>, events: &[Event], ) -> Result<()>

Archive a batch of events scoped to tenant_id and the time window [from, to]. Returns Ok(()) only if the data is durably persisted in the target.

fn description(&self) -> String

Human-readable description of the backend, for logging. Defaults to the Debug representation.

impl Debug for LocalFsArchive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
