Uses of MapReduceOptions in org.springframework.data.mongodb.core.mapreduce

Methods in org.springframework.data.mongodb.core.mapreduce that return MapReduceOptions

Modifier and Type	Method and Description
MapReduceOptions	MapReduceOptions.extraOption(String key, Object value) Add additional extra options that may not have a method on this class.
MapReduceOptions	MapReduceOptions.finalizeFunction(String finalizeFunction) Sets the finalize function
MapReduceOptions	MapReduceOptions.javaScriptMode(boolean javaScriptMode) Flag that toggles behavior in the map-reduce operation so as to avoid intermediate conversion to BSON between the map and reduce steps.
MapReduceOptions	MapReduceOptions.limit(int limit) Limit the number of objects to return from the collection that is fed into the map reduce operation Often used in conjunction with a query and sort option so as to reduce the portion of the data that will be processed.
static MapReduceOptions	MapReduceOptions.options() Static factory method to create a MapReduceOptions instance
MapReduceOptions	MapReduceOptions.outputCollection(String collectionName) The collection where the results from the map-reduce operation will be stored.
MapReduceOptions	MapReduceOptions.outputDatabase(String outputDatabase) The database where the results from the map-reduce operation will be stored.
MapReduceOptions	MapReduceOptions.outputSharded(boolean outputShared) If true and combined with an output mode that writes to a collection, the output collection will be sharded using the _id field.
MapReduceOptions	MapReduceOptions.outputTypeInline() With this option, no collection will be created, and the whole map-reduce operation will happen in RAM.
MapReduceOptions	MapReduceOptions.outputTypeMerge() This option will merge new data into the old output collection.
MapReduceOptions	MapReduceOptions.outputTypeReduce() If documents exists for a given key in the result set and in the old collection, then a reduce operation (using the specified reduce function) will be performed on the two values and the result will be written to the output collection.
MapReduceOptions	MapReduceOptions.outputTypeReplace() The output will be inserted into a collection which will atomically replace any existing collection with the same name.
MapReduceOptions	MapReduceOptions.scopeVariables(Map<String,Object> scopeVariables) Key-value pairs that are placed into JavaScript global scope and can be accessed from map, reduce, and finalize scripts.
MapReduceOptions	MapReduceOptions.verbose(boolean verbose) Flag to set that will provide statistics on job execution time.
