regroup
aims to combine tables among a group of workers. All workers should run it concurrently. The defination of the method is:
boolean regroupCombine(final String contextName, String operationName, Table<P> table, Partitioner partitioner, DataMap dataMap, Workers workers)
contextName
— the name of the contextoperationName
— the name of the operationtable
— the name of the data tablepartitioner
— the partitionerdataMap
— the data mapworkers
— the workers
Example
regroupCombine(contextName, "regroup", table, new Partitioner(workers.getNumWorkers()), dataMap, workers);
