Getting the Most Out of Impala
We tested Cloudera Impala in an effort to understand what hardware setup would provide the best performance/price for it. Our aim is to provide a quick practical guide for choosing the infrastructure to run Impala on.
- Query Execution Times
Results for a set of 20 queries run on the same data set, ten times on each hardware configuration.
- Single vs. Dual-CPU Instances
We weren't expecting dramatic score changes between single and dual-CPU instances, but what we found was surprising.
- Performance/Price Scores
Using our standard cost structure, we added the price per hour for each instance and paired it with the Impala performance score.
