Re: OutOfMemoryException with Persistence and Eviction Enabled

I tried doubling it from 200 MB to 400 MB. My initial test worked, but as I increased the number of fields that I was writing per entry, the same issue occurred again. So it seems to just increase the capacity of what can be written, not actually prevent the exception from occurring. I guess my

Re: [DISCUSSION] Renaming Ignite's product category

Adam, Like your way of thinking. It makes sense to me. For me, a computing platform comprises two essential components - a storage engine and compute APIs (not only compute grid, but also streaming, SQL, etc.). Under this definition, Ignite fits the "compute platform" category for sure, but the p

Re: IgniteCache.size() is hanging

Hi, Highly likely some of the nodes go offline and try to connect again. Probably you had some network issues. I think I will see this and other information in the logs. Can you provide them? BR, Andrei 9/24/2020 6:54 PM, Alan Ward пишет: The only log I see is from one of the server nodes, w

Re: IgniteCache.size() is hanging

The only log I see is from one of the server nodes, which is spewing at a very high rate: [grid-nio-worker-tcp-comm-...][TcpCommunicationSpi] Accepted incoming communication connection [locAddr=/:47100, rmtAddr=: Note that each time the log is printed, i see a different value for . Also note th

Re: OutOfMemoryException with Persistence and Eviction Enabled

Hi, Did you try to increase the DataRegion size a little bit? It looks like 190 MB isn't enough for some internal structures that Ignite stores in OFF-HEAP except the data. I suggest you increase the data region size to for example 512 MB - 1024 MB and take a look at how it will work. If y

IgniteCache.size() is hanging

[image: Selected post] I'm running a 5 node Ignite cluster, version 2.8.1, with persistence enabled and a small number of partitioned caches, ranging between a few thousand records to one cache with over 1 billion records. No SQL use. When I run a Java client app and connect to the cluster (with c

Re: Issue in Alter Table - Drop Column functionality

Hi Ilya, Thank you for the confirmation and the workaround is working as expected. Much appreciated. Is there any rough release date or release version for this issue? Regards, Shravya Nethula, BigData Developer, [cid:357d40f2-e612-4cef-b899-fb17a36896bb] Hyderabad. _

Re: Issue in Alter Table - Drop Column functionality

Hello! Thank you for this report, now I can indeed confirm I can see the issue! I have filed https://issues.apache.org/jira/browse/IGNITE-13482 on your behalf. As a workaround you can do SELECT * FROM tbl LIMIT 0; before issuing ALTER TABLE on that node. Regards, -- Ilya Kasnacheev чт, 24 сен

Re: Issue in Alter Table - Drop Column functionality

Hi Ilya, Yes, the code that you sent is working fine. But can you please try the below code, by executing CREATE TABLE and ALTER TABLE in separate programs. In this scenario, its not working. public class ClientNode { public static void main(String[] args) { IgniteConfiguration igni
