Struct LakehouseByteCache 

pub struct LakehouseByteCache { /* private fields */ }

Local byte cache for s3:// Parquet objects.

Only an object with an ETag or version is served from or filled into the cache; its entry is keyed by that identity, the bucket and endpoint, and the object location.

Implementations

impl LakehouseByteCache

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

A cache under root that serves complete entries and never fills.

pub fn with_fill(self, fill: LakehouseByteCacheFill) -> Self

Selects when a miss is filled.

pub fn ignoring_hits(self) -> Self

Reads every object remotely even when a complete entry exists, for benchmark isolation. Misses are still filled as Self::with_fill selects.

pub fn with_max_retained_bytes(self, bytes: NonZeroU64) -> Self

Best-effort byte target the cache root is trimmed toward.
