This load balancer performs simple round-robin for read and write queries execution. author:    Emmanuel Cecchet version:    1.0 Constructor Summary public   ParallelDB_RR(VirtualDatabase vdb)      Method Summary public  DatabaseBackend chooseBackendForReadRequest(AbstractRequest request)      Choose a backend using a round-robin algorithm for read request execution. public  DatabaseBackend chooseBackendForWriteRequest(AbstractWriteRequest request)      Choose a backend using a round-robin algorithm for write request execution. public  String getInformation()      public  String getParallelDBXml()      Constructor Detail ParallelDB_RR public ParallelDB_RR(VirtualDatabase vdb) throws Exception(Code) Creates a new ParallelDB_RR object Parameters:   vdb - the virtual database this load balancer belongs to. throws:   Exception - if an error occurs Method Detail chooseBackendForReadRequest public DatabaseBackend chooseBackendForReadRequest(AbstractRequest request) throws SQLException(Code) Choose a backend using a round-robin algorithm for read request execution. Parameters:   request - request to execute the chosen backend throws:   SQLException - if an error occurs chooseBackendForWriteRequest public DatabaseBackend chooseBackendForWriteRequest(AbstractWriteRequest request) throws SQLException(Code) Choose a backend using a round-robin algorithm for write request execution.
