This directory contains an idiomatic C++ client library for the Datastream API, a serverless and easy-to-use change data capture (CDC) and replication service. It allows you to synchronize data across heterogeneous databases and applications reliably, and with minimal latency and downtime.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.
For detailed instructions on how to build and install this library, see the top-level README.
#include "google/cloud/datastream/datastream_client.h"

int main(int argc, char* argv[]) try {
if (argc != 3) {

return 1;
}
namespace datastream = ::google::cloud::datastream;
auto client =
datastream::DatastreamClient(datastream::MakeDatastreamConnection());

std::string{"projects/"} + argv[1] + "/locations/" + argv[2];

if (!r) throw std::move(r).status();
