Thanks Denis. Yes, I know about this setting. Actually, the problem really is that when a client is trying to 1. Reconnect after a problem 2. Or even just connect for the first time on start up Then the updates to other nodes will pause while this new client is joining the cluster. Is ther

Hi, It might be an issue with deactivation. Try update to 2.6 or wait 2.7. Right now just skip cluster deactivation. Once you formed a baseline topology and finished loading data, just enable WAL log for all caches. When log enabled successfully, you can safely stop nodes. On next time when all b

Re: Additional field problems occurred in ignite2.6

Gordon, Client nodes are not developed to be used on user side of the application. Thin client should be used instead: https://apacheignite-net.readme.io/docs/thin-client Also ODBC client may be an option here: https://apacheignite-sql.readme.io/docs/odbc-driver Denis пт, 3 авг. 2018 г. в 10:13,

Contribution on Ignite

Hi Igniters, I want to thank you because, my distrubuted closures are working perfectly! Now I'd like to do a step further. What I really need are the API for Service in C++. I already know that are missing, and maybe C++ is not your first thought. So, I'd like to try to contribute to the project t

The Apache Ignite book - I have some confusion when reading?

Actually, we deployed the service at 02:00, and didn’t use the service until 16:27 the next day. Then got the error. There were more than 12 hours in between. Does this still seem related to IGNITE-1478 ? If not, can you think of other possibl

Re: SQL SELECT with AffinityKeyMapped - no results

Floris, Most probably, you hit a bug, that was introduced in Ignite 2.0: https://issues.apache.org/jira/browse/IGNITE-5795 Because of this bug @AffinityKeyMapped annotation is ignored in classes, that are used in query entity configuration. As far as I can see, this is exactly your case. It's go

Re: SQL SELECT with AffinityKeyMapped - no results

Floris, Binary metadata may be saved in work/binary_meta directory. Try cleaning this directory and see if it helps. You will also need to restart the whole cluster. Note, that it may lead to impossibility to read persisted data, if you have any. Denis пт, 3 авг. 2018 г. в 18:15, Floris Van Nee

Re: Delete/remove cache does not free the memory in PCF server

I don't see any issue here. The Ignite process shows max virtual memory size [1] allocated by your operating system (OS) for it during the peak usage. The data region just grew to that size, and once you remove all the data, it will be empty (just call cache.size() to confirm this). So, Ignite as
