There was a problem hiding this comment.
In the Status SchemaTabletsScanner::_fill_block_impl(vectorized::Block* block){}, you can add a lambda function like:
auto fill_column = [&](int column_index, auto data_extractor) {
using ValueType = std::remove_reference_t<decltype(data_extractor(_tablets[0]))>;
std::vector<ValueType> srcs(fill_tablets_num);
for (size_t i = 0; i < fill_tablets_num; ++i) {
TabletSharedPtr tablet = _tablets[fill_idx_begin + i];
srcs[i] = data_extractor(tablet);
datas[i] = &srcs[i];
}
return fill_dest_column_for_range(block, column_index, datas);
};
Then you could call it to make the code more concise like:
RETURN_IF_ERROR(fill_column(0, [this](auto tablet) { return _backend_id; }));
RETURN_IF_ERROR(fill_column(1, [](auto tablet) { return tablet->tablet_meta()->table_id(); }));
...
