Small Selectivities Matter: Lifting the Burden of Empty Samples
Summary: Addresses zero-tuple selectivities in sampling-based cardinality estimation with a novel approach compatible with any DBMS capable of sampling. Shows up to two orders of magnitude reduction in estimation error and 1.3-1.8x faster responses for complex filters, with negligible impact on optimization time.
