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 context
  • operationName — the name of the operation
  • table — the name of the data table
  • partitioner — the partitioner
  • dataMap — the data map
  • workers — the workers


regroupCombine(contextName, "regroup", table, new Partitioner(workers.getNumWorkers()), dataMap, workers);
