ColumnStoreWriteHints

Struct ColumnStoreWriteHints 

Source
pub struct ColumnStoreWriteHints {
    pub target_chunk_bytes: usize,
    pub recommended_insert_batch_rows: usize,
    pub max_insert_batch_rows: usize,
    pub varwidth_fallback_rows_per_slice: usize,
}
Expand description

Heuristics that guide callers when sizing write batches for the column store.

The values are derived from the store’s ingest configuration so higher layers can adapt without duplicating storage-level constants. Callers should treat these numbers as soft targets: exceeding the maximum batch rows will be clamped, but smaller batches are always accepted.

Fields§

§target_chunk_bytes: usize

Target chunk size used when splitting incoming arrays.

§recommended_insert_batch_rows: usize

Preferred number of rows to buffer per insert before flushing.

§max_insert_batch_rows: usize

Hard ceiling for literal INSERT batches before storage splits them eagerly.

§varwidth_fallback_rows_per_slice: usize

Fallback slice size for exotic variable-width arrays lacking offset metadata.
