Abstract
Generating queries in a heterogeneous cloud computing environment is provided. The method comprises transforming disparate statistical formats into a unified representation to standardize statistical metadata between relational databases and NoSQL databases. SQL-derived NoSQL statistics are integrated into a unified repository according to the unified representation. Mapped NoSQL statistics are integrated into relational database query optimizers. An optimal predicate pushdown strategy and an execution plan for a query across heterogeneous databases are determined according to the standardized statistical metadata. The query to the heterogeneous databases is then executed according to the relational database query optimizers and the optimal pushdown strategy and execution plan.
