Struct NodeGroup 

pub struct NodeGroup { /* private fields */ }

A node group holds up to NODE_GROUP_SIZE (131,072) rows, organized as a collection of ChunkedNodeGroups (each 2,048 rows).

Implementations

impl NodeGroup

pub fn new(node_group_idx: NodeGroupIdx, data_types: Vec<LogicalType>) -> Self

Create a new node group with default capacity (NODE_GROUP_SIZE).

pub fn with_capacity( node_group_idx: NodeGroupIdx, data_types: Vec<LogicalType>, capacity: u64, ) -> Self

Create a node group with a custom capacity.

pub fn node_group_idx(&self) -> NodeGroupIdx

pub fn format(&self) -> NodeGroupFormat

pub fn set_format(&mut self, format: NodeGroupFormat)

pub fn data_types(&self) -> &[LogicalType]

pub fn num_rows(&self) -> u64

pub fn capacity(&self) -> u64

pub fn is_full(&self) -> bool

pub fn num_chunked_groups(&self) -> usize

pub fn chunked_group(&self, idx: usize) -> &ChunkedNodeGroup

pub fn chunked_group_mut(&mut self, idx: usize) -> &mut ChunkedNodeGroup

pub fn global_row_to_chunked_group(&self, row: u64) -> (usize, u64)

Map a global row index to (chunked_group_idx, local_row_within_group).

pub fn append_row(&mut self, values: &[Option<&[u8]>]) -> u64

Append a row of raw byte values across all columns. Automatically creates new ChunkedNodeGroups as needed. Returns the global row index within the node group.
