You can refer to the javadocs of these interfaces to get an idea behind these classes. AggregatorFactory is what you use to get a off-heap aggregator or an on-heap aggregator or a vector aggregator (off-heap). Depending on the use case (ingestion vs query), query engine (topn, grouping), one of on-heap or off-heap aggregator can be used. When you are building a new kind of aggregation, you will be making all these flavours available so that your aggregation can work in various different settings. -- This is an automated message from the Apache Git Service.
