pub async fn delete_expr(dataset: &mut Dataset, expr: Expr) -> Result<u64>Expand description
Delete the rows that match expr, a DataFusion filter on the Lance
table columns.
Lance gets expr with no change. Unlike crate::NdScanner::filter_expr,
a delete does not change value parts into stats filters, because a stats
filter keeps rows that do not match. Returns the number of deleted rows.
