Counters for work the slot table does when groups move, from the table’s debug stats. *_count fields count operations or items summed over all operations; *_max_span fields hold the largest single operation.

Fields

subtree_move_count: usize

Subtree moves done.

moved_group_count: usize

Groups moved, summed over all subtree moves.

moved_group_max_span: usize

Most groups moved by one subtree move.

moved_payload_count: usize

Payload slots moved, summed over all subtree moves.

moved_payload_max_span: usize

Most payload slots moved by one subtree move.

moved_node_count: usize

Nodes moved, summed over all subtree moves.

moved_node_max_span: usize

Most nodes moved by one subtree move.

payload_location_range_refresh_count: usize

Times the payload locations of a range of groups were rewritten.

payload_location_range_refresh_group_count: usize

Groups covered, summed over all range refreshes of payload locations.

payload_location_range_refresh_group_max_span: usize

payload_location_range_refresh_payload_count: usize

Payload slots rewritten, summed over all range refreshes of payload locations.

payload_location_range_refresh_payload_max_span: usize

Most payload slots rewritten by one range refresh of payload locations.

payload_location_refresh_count: usize

Times the payload locations of a single group were rewritten.

payload_location_refresh_payload_count: usize

Payload slots rewritten, summed over all single-group refreshes of payload locations.

payload_location_refresh_max_span: usize

Most payload slots rewritten by one single-group refresh of payload locations.

group_index_refresh_count: usize

Times the stored group indexes behind the group anchors were rewritten.

group_index_refresh_group_count: usize

Groups covered, summed over all group index refreshes.

group_index_refresh_max_span: usize

Most groups covered by one group index refresh.

segment_range_update_count: usize

Times the cached payload and node segment ranges were updated.

segment_range_update_group_count: usize

Groups covered, summed over all segment range updates.

segment_range_update_max_span: usize

Most groups covered by one segment range update.

payload_shift_bytes: usize

Bytes the payload storage moved to insert, remove, detach, restore or reorder payloads.
