Java Heap

Hi , Why does the java heap size gets doubled whenever a node is joined in case of Baseline Topology. Below is the snapshot [11:13:05] Topology snapshot [ver=1, locNode=aa42b819, servers=1, clients=0, state=INACTIVE, CPUs=1, offheap=0.39GB, heap=0.97GB] QObject::startTimer: Timers cannot be start

Re: Ignite client node hangs while IgniteAtomicLong is created

Hello Ilya, I have a look at your logs and thread dumps. This definitely a bug. The data structure processor does not properly initialize when a client node connects to a cluster that changes its own state (state transition from the inactive state to active). I have created a ticket in order to ad

Resource leak of ScanQueryIterator instances

Greetings, we have came across a resource leak involving ScanQueryIterator instances. The code presumably causing the leak is along the following lines: public List> someMethod() { Iterator> iter = someIgniteCache.iterator(); List> entities = new ArrayList<>(); while (iter.hasNext()) {

Re: Java Heap

Hello! This is a cluster-wide value. Your heap doubled because you have two nodes now, each of 0.97GB. Regards, -- Ilya Kasnacheev вт, 11 авг. 2020 г. в 10:50, Ali Bagewadi : > Hi , > Why does the java heap size gets doubled whenever a node is joined in case > of Baseline Topology. > > Below

Re: Local node is not included in Baseline Topology and will not be used for data storage. Use control.(sh|bat) script or IgniteCluster interface to include the node to Baseline Topology.

Hello! This happened because you activated the cluster before this server node was added to it. Once you do, you need to add nodes to baseline manually or use auto-adjust. I'm not sure there's a C++ API for activation/baseline changes. You can use control.sh for that. Regards, -- Ilya Kasnachee

Re: I have an exception while trying to send the "evt=NODE_JOINED" message

Hi, It looks like the node can't establish a connection using the Communication channel to the remote node. I would recommend checking that all ports are opened and there is no firewall. Also, you can check that connection can be established using telnet or any other tool. If you're sure, that con

Re: I have an exception while trying to send the "evt=NODE_JOINED" message

Thank you for the quick response. First of wall ,none of the servers have a firewall. And all the ignite instances are run as root, on machines that I solely run for ignite. So I really don't understand How they can have any connection permission problems at all. For now , I'll also provide the sm

Re: Operation block on Cluster recovery/rebalance.

Re: How can I find out if indexes are used in a query?

Hi, EXPLAIN should show all the indexes. Are you sure that these indexes can be used for your query? You also can use USE INDEX hint to force the use of the index. Best Regards, Evgenii вт, 11 авг. 2020 г. в 16:22, Axel Luft : > EXPLIN PLAN doesn't show any indexes used although I created them.

How to remove IgniteAtomicLong using REST API?

Hi there, It seems atomic longs are stored in a special system cache as the "rmv" command doesn't really remove the key. Is there a way to remove IgniteAtomicLong using REST API? If not - what would it take to add such a command? Is there any other option like thin client? Thanks.
