There exist two protobuf runtime libraries that offer the same set of APIs, allowing developers to choose the one that best suits their needs. This package requires `google/protobuf`, which is the native implementation. It is easy to install and a good way to get started quickly. Alternatively, and the recommended option for production is to install the Protobuf C extension for PHP. The extension makes OTLP exporting *significantly* more performant. The extension can be installed with the following command: ``` pecl install protobuf ``` The extension can be installed alongside the native library, and it will be used instead if available.
