The Google Cloud Storage team is focused on providing tools to optimize AI/ML workloads.AI/ML data pipelines involve data preparation, model training, and model serving which can stress storage systems.Cloud Storage's hierarchical namespace (HNS) can enhance performance and efficiency of AI/ML workloads.HNS enables atomic and fast folder renames, aiding in checkpointing and fault tolerance.Hierarchical namespace offers benefits like optimized storage layout for higher QPS of reads and writes.Folders in HNS buckets allow for organizing data in a tree-like structure for efficient filesystem operations.Using HNS leads to up to a 20x faster checkpointing speed compared to flat namespace buckets.HNS buckets support up to 8x higher initial object read and write requests per second compared to flat buckets.Companies like AssemblyAI have seen significant improvements using HNS with Cloud Storage FUSE for AI/ML workloads.In conclusion, enabling hierarchical namespace on new buckets is recommended for AI/ML workloads.
