Scaling with SQL query

Hi,   I have a cluster of 10 nodes, and a cache with replication factor 3 and no persistency enabled. The SQL query is pretty simple -- "SELECT * FROM Logs ORDER by time DESC LIMIT 100". I have checked the index for "time" attribute is applied.   When I increase the number of nodes,

Re: Ignite on RBAC enabled K8s cluster

Hi Roman, Thanks for the information. I was able to get ignite working with RBAC enabled K8s cluster. The issue was with K8s calico networking, I had set it up wrongly because of which I was getting errors. Regards, Vishwas -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Distributed Closures Apply method/c#

Very strange. By default, there is no any timeout. I will take a look more carefully. Also is it possible that you cancel the closure somehow? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Running Node removal from baseline

Hi, Now in case of the node was left the BLT cluster will wait for it. In case if it can't return for a long time user should manually remove it from BTL and it will do rebalance like in this example:

Some of the code is proprietary, but this is the exception. No, I have not set a manual timeout System.Threading.ThreadAbortException: Thread was being aborted. at System.Threading.Monitor.ObjWait(Boolean exitContext, Int32 millisecondsTimeout, Object obj) at

Hi, Could you please provide some more details: cache configuration, an example of code that was failed and logs? BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Distributed Closures Apply method/c#

Hi, Could you please provide the exception? As I see from the code if you didn't set some timeout manual using writeTimeout method then Long.MAX_VALUE should be used. Long timeout = (Long)map.get(TC_TIMEOUT); long timeout0 = timeout == null || timeout == 0 ? Long.MAX_VALUE :

RE: Ignite Node failure - Node out of topology (SEGMENTED)

Hi Dmitry, We are again seeing segmentation failure in one of the node of our prod env. This time we did not run jmap, but still node failed. -> CPU, memory utilization and network are in optimal state. We observed that there are page faults in memory at the same time of segmentation failure,

Distributed Closures Apply method/c#

Hi all Is there a timeout implied or otherwise with Apply() method for a Distributed closure? Seems to kick out a exception after roughly two mins. Thanks -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: A series of Apache Ignite meetups in New York

Hi Dennis, Would you please consider writing a blog post on 'Ignite + kubernetes' for us folks who are not in NY? Also if you can record this session and post links later, it would be very useful. Thanks, Arun -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

RE: Deadlock during cache loading

"When receiver is invoked for key K, it’s holding the lock for K." is not correct, at least in the 2.4 code. When a custom stream receiver is called, the data streamer thread has a read-lock preventing termination, and there is a real-lock on the topology, but DataStreamerUpdateJob.call() does

Re: Ignite 2.4 & 2.5 together?

Hi, It is recommended to set baseline at first if grid was upgraded from <2.4 version. Then you need to deactivate the grid to force checkpoint, this can reduce time of next startup. Then stop grid and update jars to newer version and start the grid. Then you may be need to activate grid if it

Re: Ignite 2.4 & 2.5 together?

Hi, It should not be possible by default and highly not recommended. As there can be differences in communication protocol between versions ans compatibility is not tested. However, persistence format should be backward compatible that means Ignite newer version can work with persistence created

Re: Re-post: java.io.IOException: Too many open files

Hi, Thank you for attaching the code sample and configration. Most likely this information will be enough to reproduce the issue. Meanwhile could you please try to add `defer client.Close()` into your code: func main() { client, err := redis.DialTimeout("tcp", "10.1.14.221:11211", 500 *

Re: Re-post: java.io.IOException: Too many open files

Hi, Sorry I have no knowledge about maven. Here is my config file and sample code of the client. I reproduced "Connection reset by peer" by adjust the timeout setting, but ignite's file descriptor count didn't increase. Before ignite was halted by "Too many open files", there was a close wait

Re: Re-post: java.io.IOException: Too many open files

Hi, I checked the logs and it saw there are a lot of "Connection reset by peer" exceptions there which can be a cause of "Too many open files". It seems that the clients connect to Ignite server node via REST API. Could you please share a small reproducer (maven project at github) and server
