Why is using Unix Domain Sockets beneficial for DogStatsD?

Using Unix Domain Sockets for DogStatsD is beneficial primarily because it improves performance by bypassing the networking stack. When you send data over Unix Domain Sockets, the communication occurs entirely within the operating system, which allows for faster data transfer compared to traditional network protocols that involve a more complex stack, including TCP or UDP. This bypassing reduces latency and overhead, resulting in quicker message delivery and enhanced efficiency for metrics collection.

Additionally, Unix Domain Sockets offer benefits such as lower resource consumption compared to networking protocols because they do not require the overhead of network protocol processing. This direct inter-process communication can lead to more efficient handling of metrics being sent to the DogStatsD server, which is particularly important for applications generating a high volume of metrics.
