获取或创建表

获取表详细信息（如果表存在）或自动创建表（如果表不存在）。

代码示例

C++

如需了解如何安装和使用 Bigtable 的客户端库，请参阅 Bigtable 客户端库。

如需向 Bigtable 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为本地开发环境设置身份验证。

namespace cbt = ::google::cloud::bigtable;
namespace cbta = ::google::cloud::bigtable_admin;
using ::google::cloud::StatusOr;
[](cbta::BigtableTableAdminClient admin, std::string const& project_id,
   std::string const& instance_id, std::string const& table_id) {
  std::string instance_name = cbt::InstanceName(project_id, instance_id);
  std::string table_name = cbt::TableName(project_id, instance_id, table_id);

  google::bigtable::admin::v2::GetTableRequest r;
  r.set_name(table_name);
  r.set_view(google::bigtable::admin::v2::Table::FULL);

  StatusOr<google::bigtable::admin::v2::Table> table = admin.GetTable(r);
  if (!table &&
      table.status().code() == google::cloud::StatusCode::kNotFound) {
    // The table does not exist, try to create the table.
    table = admin.CreateTable(instance_name, table_id, {});
    if (!table) throw std::move(table).status();
    // The schema returned by a `CreateTable()` request does not include all
    // the metadata for a table, we need to explicitly request the rest:
    table = admin.GetTable(std::move(r));
  }
  if (!table) throw std::move(table).status();
  std::cout << "Table metadata: " << table->DebugString() << "\n";
}
