Aleph::CA::Checkpoint_Options Struct Reference

User-tunable knobs for save_checkpoint. More...

#include <ca-checkpoint.H>

Public Attributes
bool	compress = false
	Enable DEFLATE compression of the frame payload.
int	level = 6
	DEFLATE level in [1, 9]. 0 falls back to 6.
bool	sync_dir = true
	Call fsync on the parent directory after the atomic rename.

Detailed Description

User-tunable knobs for save_checkpoint.

Defaults preserve the Phase 15 behaviour (raw, uncompressed bytes, no fsync on the parent directory). Phase 17 callers that care about crash safety should keep sync_dir = true.

level

int Aleph::CA::Checkpoint_Options::level = 6

DEFLATE level in [1, 9]. 0 falls back to 6.

sync_dir

bool Aleph::CA::Checkpoint_Options::sync_dir = true

Call fsync on the parent directory after the atomic rename.

Costly but required for survival across kernel crashes.
