Summary:A request that includes a syntax tree is received. A query plan that comprising one or more queries using storage metadata and one or more data attributes obtained from the syntax tree is generated. Individual ones of the one or more queries are used to retrieve at least one of the one or more data attributes from the at least two datastores. The generating of the query plan is generated by modifying individual ones of the one or more queries to access a datastore of the at least two datastores having a lower data retrieval latency. The one or more queries of the query plan are executed to generate the report, the report including data resulting from the executing of the one or more queries.
