The Analyzer collects Presto and Trino workload statistics, and analyzes them. The analysis report provides improved visibility into your analytical workloads, and enables query optimization – to enhance cluster performance.
The Analyzer collects, and stores, QueryInfo JSONs for queries executed while it is running, and any historical queries held in the Presto Coordinator memory. The collection process has negligible compute-costs, and does not impact cluster query execution in any way. Ensure that sufficient disk space is available in your working directory. Typically, a compressed JSON file size will be 50kb – 200kb.
