Workbook ingest limits applied by loader backends before they materialize large sheets.

Fields

max_sheet_rows: u32

Hard cap for declared/logical sheet rows.

max_sheet_cols: u32

Hard cap for declared/logical sheet columns.

max_sheet_logical_cells: u64

Hard cap for the rectangular logical area a backend may materialize.

max_formula_plane_fallback_cells: u64

Hard cap for formulas materialized by one FormulaPlane fallback.

sparse_sheet_cell_threshold: u64

Sparse-sheet checks only trigger once a sheet reaches this many logical cells.

max_sparse_cell_ratio: u64

Maximum allowed logical-to-populated-cell ratio once the sparse threshold is crossed.

max_formula_spool_bytes_per_sheet: u64

Maximum encoded formula replay bytes retained for one sheet.

max_formula_spool_bytes_per_workbook: u64

Maximum encoded formula replay bytes produced across one workbook load.

max_formula_spool_files_per_workbook: u32

Maximum number of native spill files created across one workbook load.

formula_spool_memory_prefix_bytes: u64

Encoded bytes retained in memory before native spill.

max_formula_spool_memory_bytes: u64

Independent cap for a memory-only formula replay spool.

formula_spool_disk_policy: FormulaSpoolDiskPolicy

Whether formula replay data may use secure native temporary storage.
