Struct IceDiskRelTable 

pub struct IceDiskRelTable {
    pub name: String,
    pub layout: IceDiskRelTableLayout,
    pub indices_file_path: PathBuf,
    pub indptr_file_path: Option<PathBuf>,
}

The ICE (IceDisk) native disk format for relationship tables. Based on Ladybug’s IceDiskRelTable implementation, which stores relational data directly in Parquet format files (indices.parquet and optionally indptr.parquet).

Fields

name: String

layout: IceDiskRelTableLayout

indices_file_path: PathBuf

indptr_file_path: Option<PathBuf>

Implementations

impl IceDiskRelTable

pub fn new( name: String, base_path: &Path, layout: IceDiskRelTableLayout, ) -> Self

Initialize a new IceDiskRelTable pointing to its Parquet files.

pub fn scan_indices( &self, vfs: &VirtualFileSystemRegistry, columns: &[CatalogColumn], ) -> Result<IceDiskRelTableScanState, ParquetReaderError>

Scan the indices parquet file and return a streaming scan state.

pub fn scan_indptr( &self, vfs: &VirtualFileSystemRegistry, columns: &[CatalogColumn], ) -> Result<Vec<Vec<Value>>, ParquetReaderError>

Scan the indptr parquet file (if using CSR layout).
