public static interface QueryRecord.PartialResult.Step
A QueryRecord.Step carries the recorded cost of evaluating a filter as part of a query operation. This cost may be the estimated or actual execution cost depending on the type
of the recorder
in use when the step was created.
Method Summary | |
---|---|
long |
getDuration() Get the amount of time (in ms) spent evaluating the filter or applying an index for this query plan step. |
int |
getEfficiency() Get the calculated cost of applying the filter as defined by calculateEffectiveness |
java.lang.String |
getFilterDescription() Get a description of the filter that was associated with this step during its creation. |
java.util.Set |
getIndexLookupRecords() Get the recorded information about the index lookups performed during filter evaluation as part of a query record. |
int |
getPostFilterKeySetSize() Get the size of the key set remaining after evaluating the filter or applying an index. |
int |
getPreFilterKeySetSize() Get the size of the key set prior to evaluating the filter or applying an index. |
java.util.List |
getSteps() Return inner nested steps, may be null if not nested. |
