Detailed Description

ConflictData is a helper struct tracking conflicts for each index in a chunk, as well as the total conflict count, and the row ID matching each conflict.

Insert()

void duckdb::ConflictManager::ConflictData::Insert ( const idx_t  index_in_chunk, const row_t  row_id  )

inline

Inserts a conflict into the two selection vectors, the row IDs, and the validity.

                                                                    {
            D_ASSERT(!validity.RowIsValid(index_in_chunk));
            sel->set_index(index_in_chunk, count);
            inverted_sel->set_index(count, index_in_chunk);
            validity.SetValid(index_in_chunk);
            row_ids_data[count] = row_id;
            count++;
        }

GetRowId()

row_t duckdb::ConflictManager::ConflictData::GetRowId ( const idx_t  index_in_chunk )

inline

Returns the row ID matching the index in the chunk.

                                                   {
            D_ASSERT(validity.RowIsValid(index_in_chunk));
            auto idx = sel->get_index(index_in_chunk);
            return row_ids_data[idx];
        }

Here is the call graph for this function:

Reset()

void duckdb::ConflictManager::ConflictData::Reset ( )

inline

Resets the conflict data.

                     {
            count = 0;
            sel = nullptr;
            inverted_sel = nullptr;

            row_ids = nullptr;
        }

Member Data Documentation

validity

ValidityArray duckdb::ConflictManager::ConflictData::validity

Keeps track of the indexes in the chunk for which we've seen a conflict. True (valid) indicates a conflict.
