Join Reordering by Join Simulation

We introduce a framework for reordering join pipelines at runtime in a database system. This framework incorporates novel techniques for simulating the execution of a join pipeline using random samples and statistical summaries. Our simulation techniques provide accurate runtime cardinality estimate...
