Module wal 

Append-only write-ahead log for committed state snapshots.

A frame is considered committed only after its complete header, payload, and checksums have reached the WAL file. Recovery accepts valid complete frames and repairs and ignores an incomplete final frame, which is the normal result of a killed process during append.

Structs

Frame

Constants

MAX_WAL_BYTES

Return the highest valid frame. A partial/corrupt tail is ignored; an invalid frame before the tail is an error because it would hide later data.
