- Record Components:
nullsFiltered- iftrue, then target docs passed from the source operator are guaranteed to have a value for the field; otherwise, the guarantee is unknown. This enables optimizations for block loaders, treating the field as dense (every document has value) even if it is sparse in the index. For example, "FROM index | WHERE x != null | STATS sum(x)", after filtering out documents without value for field x, all target documents returned from the source operator will have a value for field x whether x is dense or sparse in the index.blockLoader- maps shard index to theBlockLoaders which load the actual blocks.

Method Details
-
toString
Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components. -
hashCode
public final int hashCode()Returns a hash code value for this object. The value is derived from the hash code of each of the record components. -
equals
Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared withObjects::equals(Object,Object); primitive components are compared with '=='. -
name
Returns the value of thenamerecord component.- Returns:
- the value of the
namerecord component
-
type
Returns the value of thetyperecord component.- Returns:
- the value of the
typerecord component
-
nullsFiltered
public boolean nullsFiltered()Returns the value of thenullsFilteredrecord component.- Returns:
- the value of the
nullsFilteredrecord component
-
blockLoader
Returns the value of theblockLoaderrecord component.- Returns:
- the value of the
blockLoaderrecord component
