@mainpage AlloyDB API C++ Client Library

An idiomatic C++ client library for the [AlloyDB API][cloud-service-docs].
AlloyDB for PostgreSQL is an open source-compatible database service that
provides a powerful option for migrating, modernizing, or building
commercial-grade applications. It offers full compatibility with standard
PostgreSQL, and is more than 4x faster for transactional workloads and up to
100x faster for analytical queries than standard PostgreSQL in our performance
tests. AlloyDB for PostgreSQL offers a 99.99 percent availability SLA inclusive
of maintenance.

AlloyDB is optimized for the most demanding use cases, allowing you to build new
applications that require high transaction throughput, large database sizes, or
multiple read resources; scale existing PostgreSQL workloads with no application
changes; and modernize legacy proprietary databases.

While this library is **GA**, please note that the Google Cloud C++ client
libraries do **not** follow [Semantic Versioning](https://semver.org/).

## Quickstart

The following shows the code that you'll run in the
`google/cloud/alloydb/quickstart/` directory,
which should give you a taste of the AlloyDB API C++ client library API.

## Main classes

<!-- inject-client-list-start -->
The main class in this library is
[`alloydb_v1::AlloyDBAdminClient`](@ref google::cloud::alloydb_v1::AlloyDBAdminClient). All RPCs are exposed
as member functions of this class. Other classes provide helpers, configuration
parameters, and infrastructure to mock
[`alloydb_v1::AlloyDBAdminClient`](@ref google::cloud::alloydb_v1::AlloyDBAdminClient) when testing your
application.
<!-- inject-client-list-end -->
