Dxfs-delayed-logging-design.txt302 size of a checkpoint to be slightly less than a half the log.
304 Apart from this size requirement, a checkpoint transaction looks no different
307 perspective, the checkpoint transaction is also no different - just a lot
311 Because the checkpoint is just another transaction and all the changes to log
314 minimise the time we hold the CIL locked while writing the checkpoint
318 per-checkpoint context that travels through the log write process through to
319 checkpoint completion.
321 Hence a checkpoint has a context that tracks the state of the current
322 checkpoint from initiation to checkpoint completion. A new context is initiated
323 at the same time a checkpoint transaction is started. That is, when we remove
