Summary
@cache.secure inherits the default serializer and the encryption guard rejects any non-default serializer, so it always
wraps StandardSerializer (msgpack), which hard-rejects DataFrames. The entire ...

Summary
Two sync-vs-async asymmetries on the L2 hit path:
1. No L1 backfill on sync L2 hit. The async wrapper re-warms L1 on every L2 hit; the sync wrapper does not. After L1
eviction/restart, sync ...

Summary
Four config settings are defined (and some validated) but never actually consumed:
1. l1_max_size_mb / L1CacheConfig.max_size_mb — never passed to L1Cache; the manager hardcodes 100 MB. Configuring ...

Summary
unwrap() does payload = bytes(mv[header_end:]) — a full copy of the payload out of the CK frame on every deserialize,
including every L1 hit (L1 stores the framed envelope). For a 300 MB DataFrame ...

Summary
_bounded_chunksize uses a uniform average bytes_per_row = table.nbytes // table.num_rows and caps batches by row count
only. For variable-width/skewed frames (e.g. a JSON-blob column, clustered ...

Summary
The msgpack columnar DataFrame fallback (used when pyarrow is absent and serializer= auto ) branches on
series.dtype.name.startswith( int )/( float ) — lowercase. Pandas nullable dtypes are capitalized ...

python
Summary
On deserialize/integrity failure, the L1 path invalidates the entry (self-heals), but the L2 path catches
SerializationError and returns None (miss → recompute) without deleting the corrupt/tampered ...

Summary
A NaN TTL produces expires_at = NaN. The store guard if expiry = current_time and is_expired() s time.time() =
expires_at both evaluate False for NaN, so the entry is stored and never expires ...

Summary
np.frombuffer is used to reconstruct numpy arrays and numeric DataFrame/Series columns. The returned arrays are
writeable=False, owndata=False, and alias the source bytes. On an L1 hit they alias ...

python
Summary
The dataframe/series deserialize branches wrap ByteStorage.retrieve in a broad except Exception that logs at DEBUG and
falls through to re-parsing the (still-corrupt) bytes as raw msgpack. A genuine ...
