Worker Affinity with Task Queues allows ensuring that multiple Activities within a workflow execute on the same Worker. This is achieved by using a combination of shared and unique task queues. The workflow first discovers an available worker via a shared queue and then routes all subsequent activities to that worker's unique queue, maintaining data locality for scenarios like file processing, ML model caching, and database connection pooling.
