Struct VectorizedOperationBuffers

struct VectorizedOperationBuffers {
    append_row_indices: Vec<usize>,
    equal_to_row_indices: Vec<usize>,

}

Expand description

Buffers to store intermediate results in vectorized_append and vectorized_equal_to, for reducing memory allocation

Fields§

§append_row_indices: Vec<usize>

The vectorized append row indices buffer

§equal_to_row_indices: Vec<usize>

The vectorized_equal_to row indices buffer

§equal_to_group_indices: Vec<usize>

The vectorized_equal_to group indices buffer

§equal_to_results: Vec<bool>

The vectorized_equal_to result buffer

§remaining_row_indices: Vec<usize>

The buffer for storing row indices found not equal to exist groups in group_values in vectorized_equal_to. We will perform scalarized_intern for such rows.
