Optional<QueryOptimizerPipeline> |
getOptimizerPipeline()
Get the
QueryOptimizerPipeline that this factory will inject into the EvaluationStrategy, if any. |
long |
getQuerySolutionCacheThreshold()
Get the number of query solutions the
EvaluationStrategy will keep in main memory before it attempts to
sync to a temporary disk cache. |
boolean |
isTrackResultSize()
Returns the status of the result size tracking for the query plan.
|
void |
setOptimizerPipeline(QueryOptimizerPipeline pipeline)
Set a
QueryOptimizerPipeline to be used for query execution planning by the EvaluationStrategy. |
void |
setQuerySolutionCacheThreshold(long threshold)
Set the number of query solutions the
EvaluationStrategy will keep in main memory before it attempts to
sync to a temporary disk cache. |
void |
setTrackResultSize(boolean trackResultSize)
Enable or disable results size tracking for the query plan.
