Struct ReverseScanOption (2.28.0)

Version 2.28.0 keyboard_arrow_down
Read rows in reverse order.
The rows will be streamed in reverse lexicographic order of the keys. This is particularly useful to get the last N records before a key.
This option does not affect the contents of the rows, just the order that the rows are returned.
Note:
When using this option, the order of row keys in a bigtable::RowRange
does not change. The row keys still must be supplied in lexicographic order.
namespace cbt = ::google::cloud::bigtable;
using ::google::cloud::Options;
using ::google::cloud::StatusOr;
[](cbt::Table table) {
// Read and print the rows.
auto reader = table.ReadRows(
cbt::RowRange::RightOpen("phone#5c10102", "phone#5c10103"), 3,
cbt::Filter::PassAllFilter(),
Options{}.set<cbt::ReverseScanOption>(true));
for (StatusOr<cbt::Row>& row : reader) {
if (!row) throw std::move(row).status();
PrintRow(*row);
}
}
