> Running explain on a MERGE statement with runtime filtering enabled, I see the min/max being applied on the large table, but not the bloom filter check:
> {noformat}
> explain merge into acidTbl as t using nonAcidOrcTbl s ON t.a = s.a
> WHEN MATCHED AND s.a > 8 THEN DELETE
> WHEN MATCHED THEN UPDATE SET b = 7
> WHEN NOT MATCHED THEN INSERT VALUES(s.a, s.b)
> ...
> Map 1
> Map Operator Tree:
> TableScan
> alias: t
> Statistics: Num rows: 1 Data size: 0 Basic stats: PARTIAL Column stats: NONE
> Filter Operator
> predicate: a BETWEEN DynamicValue(RS_3_s_a_min) AND DynamicValue(RS_3_s_a_max) (type: boolean)
> Statistics: Num rows: 1 Data size: 0 Basic stats: PARTIAL Column stats: NONE
