Accelerating Real-Time Analytics with Cosmos DB and GPU-Enhanced Serverless Apache Spark

Talkat Azure Cosmos DB Conf 2025 · on Tuesday, 2025-04-15· [data-engineering, machine-learning]

Shows an end-to-end pipeline that ingests streaming CSV into Azure Storage, trains an XGBoost model with Apache Spark accelerated by NVIDIA Rapids and CUDA, and writes JSON vectors into Cosmos DB where a vector container with 8,124 items is created. Local runs measure 2.38x faster locally GPU versus CPU (typical ~10x when not streaming). Deployment uses Docker images (CUDA runtime), Azure Container Apps (CPU 4 cores 8 GB, GPU 8 cores 56 GB), a shell deploy script, batch writes of 25, and local backups on failure.
