USE_BASE_INDEX

public static final QueryHintOption<Boolean> USE_BASE_INDEX

PLANNER_TABLE_ROW_COUNT

public static final QueryHintOption<Integer> PLANNER_TABLE_ROW_COUNT

PLANNER_COST_FUNCTION

public static final QueryHintOption<ICostFunction> PLANNER_COST_FUNCTION

1.4

FLATTEN_CALL_PREDICATE

public static final QueryHintOption<IFlattenCallPredicate> FLATTEN_CALL_PREDICATE

Predicate to decide whether to flatten specific positive pattern calls IFlattenCallPredicate

Since:

1.4

CALL_DELEGATION_STRATEGY

public static final QueryHintOption<ICallDelegationStrategy> CALL_DELEGATION_STRATEGY

Strategy to decide how hints (most importantly, backend selection) propagate across pattern calls. Must implement ICallDelegationStrategy.

Since:

2.1

ADORNMENT_PROVIDER

public static final QueryHintOption<IAdornmentProvider> ADORNMENT_PROVIDER

A provider of expected adornments IAdornmentProvider. The safe default is AllValidAdornments; however, the generic backend variant may safely use LazyPlanningAdornments instead.

CONSULT_SURROGATES

public static final QueryHintOption<Boolean> CONSULT_SURROGATES

Whether the search-based query backend is to use registered surrogate queries instead of derived features.

If set to false, the query evaluation will access derived features normally, and take their output at face value. Normally, this should be fine for the search-based backend (as opposed to caching backends), and come at a lower performance cost. Hence the default is false.

Setting this option to true will cause the backend to consult the surrogate query registered for a given feature, if any. Consider this if the default implementation of some features are known to be erroneous, and there are surrogates queries that would provide correct results instead.
