Connects to Cloud Bigtable's data manipulation APIs.
This class is used by the Cloud Bigtable wrappers to access Cloud Bigtable. Multiple bigtable::Table objects may share a connection via a single DataClient object. The DataClient object is configured at construction time, this configuration includes the credentials, access endpoints, default timeouts, and other gRPC configuration options. This is an interface class because it is also used as a dependency injection point in some of the tests.
Cost
Applications should avoid unnecessarily creating new objects of type DataClient. Creating a new object of this type typically requires connecting to the Cloud Bigtable servers, and performing the authentication workflows with Google Cloud Platform. These operations can take many milliseconds, therefore applications should try to reuse the same DataClient instances when possible.
