 The OSHDB API provides a flexible and powerful way to produce aggregated results that are calculated for arbitrary subsets of the data. This `aggregateBy` functionality also supports the combination of multiple such grouping functions chained after each other.
 
-When executing any of the below listed aggregateBy methods, the query's MapReducer is transformed into a [`MapAggregator`](https://docs.ohsome.org/java/oshdb/1.1.1/aggregated/org/heigit/ohsome/oshdb/api/mapreducer/MapAggregator.html) object which is (mostly) functionally equivalent to a MapReducer, with the difference that instead of returning single result values when calling any [reduce](map-reduce.md#reduce) method, an associative list of multiple values is returned instead: The result contains one entry for each requested grouping.

 Alternatively, the OSHDB data can also be stored in any JDBC compatible database (e.g. a [PostgreSQL](https://www.postgresql.org/) database). The OSHDB data is however always processed and analyzed locally on the machine from which the OSHDB query is started. It is therefore advisable to keep the OSHDB data as local as possible in order to minimize network traffic when using the OSHDBJdbc backend.

-The [`OSHDBIgnite`](https://docs.ohsome.org/java/oshdb/1.1.1/aggregated/org/heigit/ohsome/oshdb/api/db/OSHDBIgnite.html) backend executes computations on a distributed cluster of computers running the [Apache Ignite](https://ignite.apache.org/) big data platform. Each of the computers of the cluster only holds a subset of the global OSHDB data set and can therefore execute its part of an OSHDB query more quickly than a single computer having to process the whole data set.
