    Options Description

    max_checkpoints

    The expected maximum number of checkpoints in each vBucket on a balanced system.

    NOTE: This value does not act as a hard limit for a single vBucket. The system uses it along with checkpoint_memory_ratio to compute checkpoint_max_size, which triggers checkpoint creation.

    checkpoint_memory_ratio

    Maximum portion of the bucket quota that the system can allocate to checkpoints.

    checkpoint_memory_recovery_upper_mark

    Fraction of the checkpoint quota computed by checkpoint_memory_ratio that triggers an attempt to release memory from checkpoints.

    checkpoint_memory_recovery_lower_mark

    Fraction of the checkpoint quota computed by checkpoint_memory_ratio that represents the target for checkpoint memory recovery. Memory recovery stops when this target is reached.

    checkpoint_max_size

    Maximum size in bytes of a single checkpoint. Use 0 to allow ep-engine to configure this value automatically.

    checkpoint_destruction_tasks

    Number of background tasks that destroy closed and unreferenced checkpoints to free memory.
