Velox Query Tracing

TL;DR
The query trace tool helps analyze and debug query performance and correctness issues. It helps prevent interference from external noise in a production environment (such as storage, network, etc.) by allowing replay of a part of the query plan and dataset in an isolated environment, such as a local machine. This is much more efficient for query performance analysis and issue debugging, as it eliminates the need to replay the whole query in a production environment.
