Google Cloud Platform Bigtable C++ Client Library

Cloud Bigtable is Google's NoSQL Big Data database service. It's the same database that powers many core Google services, including Search, Analytics, Maps, and Gmail.

The Cloud Bigtable C++ Client library offers types and functions to access Cloud Bigtable from C++ applications. It offers access to the Cloud Bigtable API, including admin operations to list, read, write, and delete Instances, Clusters, Tables, and Application Profiles.

Quickstart

The following "Hello World" program should give you a sense of how to use the library.

#include "google/cloud/bigtable/table.h"

int main(int argc, char* argv[]) try {
  if (argc != 4) {
    std::string const cmd = argv[0];
    auto last_slash = std::string(cmd).find_last_of('/');
    std::cerr << "Usage: " << cmd.substr(last_slash + 1)
              << " <project_id> <instance_id> <table_id>\n";
    return 1;
  }

  std::string const project_id = argv[1];
  std::string const instance_id = argv[2];
  std::string const table_id = argv[3];

  // Create a namespace alias to make the code easier to read.
  namespace cbt = ::google::cloud::bigtable;

  cbt::Table table(cbt::MakeDataConnection(),
                   cbt::TableResource(project_id, instance_id, table_id));

  std::string row_key = "r1";
  std::string column_family = "cf1";

  std::cout << "Getting a single row by row key:" << std::flush;
  google::cloud::StatusOr<std::pair<bool, cbt::Row>> result =
      table.ReadRow(row_key, cbt::Filter::FamilyRegex(column_family));
  if (!result) throw std::move(result).status();
  if (!result->first) {
    std::cout << "Cannot find row " << row_key << " in the table: " << table_id
              << "\n";
    return 0;
  }

  cbt::Cell const& cell = result->second.cells().front();
  std::cout << cell.family_name() << ":" << cell.column_qualifier() << "    @ "
            << cell.timestamp().count() << "us\n"
            << '"' << cell.value() << '"' << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
