Model training is a time-consuming, data-intensive, and resource-hungry phase in machine learning, with much use of storage, CPUs, and GPUs. The data access pattern in training requires frequent I/O of a massive number of small files, such as images and audio files. With the advancement of distributed training in the cloud, it is challenging to maintain the I/O throughput to keep expensive GPUs highly utilized without waiting for access to data. The unique data access patterns and I/O challenges associated with model training compared to traditional data analytics necessitate a change in the architecture of your data platform.
