Package org.apache.druid.query.groupby.epinephelinae.vector

Class VectorGroupByEngine

java.lang.Object

org.apache.druid.query.groupby.epinephelinae.vector.VectorGroupByEngine

public class VectorGroupByEngine
extends Object

Contains logic to process a groupBy query on a single StorageAdapter in a vectorized manner. This code runs on anything that processes StorageAdapter directly, typically data servers like Historicals.

Used for vectorized processing by GroupingEngine.process(GroupByQuery, StorageAdapter, GroupByQueryMetrics).

See Also:

for non-vectorized version of this logic
