Method Detail

findJoinPositions

public int[] findJoinPositions(int probePosition,
                               Page probe,
                               int probeGeometryChannel,
                               Optional<Integer> probePartitionChannel)

Returns an array of addresses from PagesIndex.valueAddresses corresponding to rows with matching geometries.

The caller is responsible for calling isJoinPositionEligible(int, int, Page) for each of these addresses to apply additional join filters.

isJoinPositionEligible

public boolean isJoinPositionEligible(int joinPosition,
                                      int probePosition,
                                      Page probe)
