    Slow DataGrid server insert




      I have developped a java client to insert into a datagrid server 300 000 Payments objects.

      I have one node (standalone.xml)


      It takes around 10 min to absorb. This is quite long.
      the code is the following :


      FileManager fm = new FileManager();

              List<Paiement> paiements = fm.readFile();

              if ((paiements == null) || (paiements.size() == 0))

                  System.out.println("nothing to print");


              { // from here, it takes 10 minutes

                  for (Paiement paie : paiements) {

                      remoteCache.putAsync(paie.getId(), paie);




      How can I decrease the time to insert this volume of object in the grid ?


      Thanks a lot !

          You should batch things and use the bulk methods (putAll) as they are more efficient.

            Thanks for your response.

            It seem interesting, I will try this.

              I'm worked on the same project, and I tested the putAll operation with 1 element into the map.


              But it throws an exception:


              org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for messageId=7 returned server error (status=0x86): org.infinispan.util.concurrent.TimeoutException: ISPN000299: Unable to acquire lock after 20 seconds for key [B0x2800 and requestor CommandUUID{address=mind7-virtual-machine, id=70}.

              Have you an Idea ?

                we found the bottleneck.

                We got in out cache this set :


                <!-- Enable indexing using the RAM Lucene directory provider -->

                                    <indexing index="ALL">

                                        <property name="default.directory_provider">ram</property>



                removing this deccrease greatly the time necessary to insert data.


                We have to investigate this.

                  Aha. Indexing does indeed slow things down.

                  A couple of things: for bulk loading you can add the SKIP_INDEXING flag:


                  RemoteCache noIndexingCache = cache.withFlags(Flag.SKIP_INDEXING);


                  and then you use the noIndexingCache to do all your put/putAlls. At the end you can fire off the Mass Indexer on the server, either through the 'mass-reindex' CLI operation, through JMX  or through the console. If you want to do it from the HotRod client, you could deploy a server task to do that.


                  Also, you should not use the "ram" directory provider as it provides really poor performance. Either use the infinispan one or the lucene filesystem-based one.

                    Can you explain me how to index my data with Mass Indexer ?

                    I found some tutoriels, but I don't know how to insert Mass Indexer into my code.
