Hello james vasanth,
There are several factors and best practices to consider. Here are some key points:
- User Type: The type of user (data scientist, data engineer, data analyst) can influence the compute configuration.
- Workload Type: Different workloads (ETL jobs, analytical workloads) have different requirements.
- Service Level Agreement (SLA): The level of SLA you need to meet can influence your configuration.
- Budget Constraints: Your budget can determine the size and type of cluster you choose.
- Compute Features: Understanding the features of Databricks compute (all-purpose compute, job compute, single-node, multi-node, on-demand, spot instances) can help you make an informed decision.
- Concurrent Queries: Databricks recommends a cluster for every 10 concurrent queries.
- Data Size: The size of your data can also influence the size of your cluster.
Your configuration decisions will require a tradeoff between cost and performance. It’s recommended to start with a smaller cluster and then monitor the performance. You can then adjust the size of the cluster as needed based on your observations.
