Re: Native persistence and upgrading

Thanks for the confirmation Stanislav. Is this compatibility kept between minors as a commitment from the team or is it just specific to the versions I mentioned? If this is a backward compatibility feature that you have intentions to maintain, I think it's worth mentioning that in the

Re: Native persistence and upgrading

Hi Dimitry and community, Is this still true? My intention is to do it between versions 2.7.6 and 2.8.1/2.9. Basically, I want to only update the docker image keeping the volumes so that I can recover the persisted data. I couldn't find documentation regarding this topic. On the other hand,

Re: client hangs forever trying to join the cluster (ClientImp joinLatch.await())

Hi, Thanks for the recommendations. in this case, both server and client didn't show memory issues (heap and available memory in the container). The GC pauses were very short too. The configured timeouts are default: clientFailureDetectionTimeout = 3 failureDetectionTimeout = 1 The

client hangs forever trying to join the cluster (ClientImp joinLatch.await())

Hello, we recently had a production incident in which our application got stuck connecting to the cluster. The *IgnitionEx start0* method was blocked for more than 24 hours waiting for that latch to be notified, but that never happened. Finally, the container was restarted in order to recover the

Re: Node is unable to join cluster because it has destroyed caches

Hi, I tried your suggestion of using a NodeFilter but, is not solving this issue. Using a NodeFilter by consistent-id in order to create the cache in only one node is creating persistence information in every node: In the node for which the filter is true (directory size 75MB):

Re: Node is unable to join cluster because it has destroyed caches

Hi, thanks for the prompt response We can have several of these caches, one for each query (is an exceptional case but, with load, there can be several simultaneously) that is being executed so we would like to preserve the persistence to take advantage of the swapping in case the amount of memory

Node is unable to join cluster because it has destroyed caches

Hi Ignite team, We have a use case where a small portion of the dataset must answer successive queries that could be relatively expensive. For this, we create a temporary cache with that small subset of the dataset and operate on that new cache. At the end of the process, that cache is destroyed.

Re: Slow cache updates with indexing module enabled

Hi Andrei, thanks for taking the time to answer my question. I will consider your suggestion if we decide to switch to a multiple tables approach that will require those JOIN considerations. But, in this case we have only 1 cache and the operation that we are executing is an update. We tried using

Slow cache updates with indexing module enabled

Hi, We are experiencing slow updates to a cache with multiple indexed fields (around 25 indexes during testing but we expect to have many more) for updates that are only changing one field. Basically, we have a customer*->belongsto->*segment relationship and we have one column per segment. Only

Configuration of IndexingSpi per cache?

Hi, Is it possible to configure a custom IndexingSpi per cache? I'd like to have a custom indexing mechanism to improve the full text capabilities but I would like to enable only in some caches. is that possible? Is it possible to configure multiple indexingSpi? Adding a custom indexingspi to

Re: BinaryObjectImpl.deserializeValue with specific ClassLoader

Hi, We are also facing this issue while trying to retrieve domain objects inside a compute task. Do you have plans to add this feature in the near future? maybe 2.7 release? regards -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Using compute().call from a Service has P2P class loading feature?

Hello, I have a question about p2p class loading. My topology is 1 dedicated server, 1 client. I have deployed a Service in the ignite client node (selecting clusterGroup forClients) from which I'm trying to execute a compute() to the server node. The IgniteCallable that I'm sending to call() is

IgniteUtils enables strictPostRedirect in a static block

Hello Igniters, We noticed that IgniteUtils class has a static initialization block (line 796 in version 2.6) in which System properties are being changed. In particular, the property "http.strictPostRedirect" is set to "true". This could change how an application behaves when referencing any

RE: Does event listener keep the order of events as they occur on the cluster?

Hi, It is not mandatory to provide a filter. For example, this will get all the events from "myCache" ContinuousQuery qry = new ContinuousQuery<>(); qry.setLocalListener(new MyEventListener()); myCache.withKeepBinary().query(qry); @IgniteAsyncCallback private class MyEventListener implements

Re: Ignite Transaction and Cache Events

Thanks for replying PRasad, I understand your approach but, I still don't get /when/ I should group all events for the same transaction. In my tests I get onSessionStart and onSessionEnd for each cache (both sharing the same cix). I would love to have a post commit hook because at that point I'm

Ignite Transaction and Cache Events

Hi, Do you know if there is mechanism to subscribe for to transaction events (pre or post commit)? My scenario is the following: I have 2 caches (A and B) that are modified in the same transaction. On the other hand, I have a third C cache whose entries are calculated based on A and B values. I
