You define a series of stages\u2014each implementing setup() for one-time initialization and process_data() for batch processing\u2014and connect them in a PipelineSpec. The framework handles resource allocation (CPUs, GPUs), autoscaling to balance throughput across stages, backpressure management to prevent memory overflow, and real-time monitoring. It supports three execution modes: streaming (recommended, all stages concurrent with dynamic worker balancing), batch (sequential, simpler but materializes intermediate data), and serving (online real-time input/output via queues). Most code is Python; autoscaling and artifact distribution logic is written in Rust for performance. The framework is designed for production workloads like video captioning, image processing, and other multi-model inference chains.","worth_installing":"Yes, with conditions. Cosmos-xenna is actively maintained and well-suited for production distributed AI pipelines on Ray. However, the package description explicitly states it is no longer under active development and recommends migration to Cosmos 3 for new projects. Install if you have an existing Cosmos-Xenna pipeline or need its specific feature set; otherwise, evaluate Cosmos 3 first. License terms are unclear and must be verified before use.
