Hello Databricks Community,
I am currently facing a challenge in configuring a cluster for training machine learning models on a dataset consisting of approximately a billion rows and 40 features. Given the volume of data, I want to ensure that the cluster is optimally configured to handle such a workload efficiently.
I would greatly appreciate insights from the community on the following:
Machine Selection: What are the key considerations when selecting machine types for the cluster? Should I prioritize memory, CPU, or GPU for specific models?
Cluster Configuration: What are the best practices for setting up the cluster configuration regarding node types and quantity? How do you decide on the balance between driver and worker nodes?
Performance Optimization: Are there specific settings or tips for optimizing Spark configurations or Databricks-specific features that you have found effective for handling large-scale data?
Cost Efficiency: How do you manage the trade-off between performance and cost? Are there specific configurations that provide a good balance?
Any examples, experiences, or resources you could share would be incredibly helpful. I am particularly interested in case studies or benchmarks that might guide the configuration process.
