Table Join Preflight API

Estimate join size and count duplicate keys, null rows and unmatched rows before running a join.

Estimate join size and count duplicate keys, null rows and unmatched rows before running a join. Supply up to 256 key tuples per side, each with the same width of one to four values. Keys are strings, safe integers, booleans or null. Matching is case-sensitive and type-sensitive, and any null prevents a match. The result lists keys that violate declared cardinality, including unmatched duplicate keys on a side that must be unique. Counts are exact for the supplied keys. No SQL execution, database access or joined rows. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
