Struct ReverseScanOption (2.17.0)
Stay organized with collections
Save and categorize content based on your preferences.
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.
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);
}
}
