Query processing engine recommendation method and system
Abstract:
Methods and systems are disclosed for providing recommendation of a query processing engine from multiple query processing engines. The method includes receiving queries by a query receiving unit, extraction of features of the query by a feature extractor, checking for a similar query in a knowledge base by an evaluator, executing the query on multiple query processing engines by a scheduler, and collecting execution statistics for each query processing engine if the similar query is not found in the knowledge base or fetching the suitable query processing engine from the knowledge base if the similar query is found in the knowledge base and executing the query on that query processing engine. The method also includes providing the recommendation of a single query processing engine from multiple query processing engines by the evaluator based on a recommendation value calculated for every query processing engine.
