Webinar: Key Deployment Strategies for Database Acceleration

Igniters, This Wednesday at 10am Pacific Time, I will be conducting a webinar devoted to different deployment strategies that can be used with Apache Ignite. I will talk about how Ignite can be used as a cache, as a data grid, how it can be integrated with databases and other data sources, etc.

Re: Fwd: Exceptions in C++ Ignite Thin Client on process exit

Do you keep an IgniteClient instance somewhere as a global/static variable? If so, this may not be the best idea, just move it somewhere where it will have a predictable lifetime and where it can be destroyed before main() is finished. Best Regards, Igor On Tue, Aug 4, 2020 at 2:19 AM Igor

Re: Fwd: Exceptions in C++ Ignite Thin Client on process exit

Dana, I think it makes sense to add the "Stop" method to the IgniteClient class, but currently all connections should terminate successfully once all the instances of the class are destructed. Also, the message does not look like a real problem to me, more like a warning. Does anyone have a clue

Re: Serialize a char array member as part of class serialization into cache - C++ API

Hi Dana, "char" type is not supported by Ignite as it may have different sign on different platforms. You can use int8_t if you want to have a byte array, or WriteString/ReadString if you want it to be a string. Also, I've re-factored your BinaryType code a little bit so it's more readable:

Re: ignite metrics - cache vs cachelocal

Hi, Cache metrics contain information from all nodes in the cluster, while cache local metrics are related to the one(local) node only. Evgenii пн, 3 авг. 2020 г. в 15:43, scottmf : > hi, > In JMX with Ignite I see cache and cachelocal metrics. What's the > difference? Many of the metrics

ignite metrics - cache vs cachelocal

hi, In JMX with Ignite I see cache and cachelocal metrics. What's the difference? Many of the metrics seem to overlap. thanks -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Ignite Web Console sign up. Not found.

The Ignite community stopped supporting Ignite Web Console some time ago and recently made a decision to discontinue the tool officially: https://issues.apache.org/jira/browse/IGNITE-13038 Please select an alternate tool. We've put together a list of potential candidates:

Re: Question in Continuous Query Remote Filter

I believe Java doc should be enough for that: https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/cache/query/ContinuousQuery.html It says: To stop receiving updates call QueryCursor.close()

Call for speakers - Virtual In-Memory Computing Summit 2020

Hi Igniters! The call for speakers is now open for the upcoming virtual In-Memory Computing Summit scheduled for October 28-29, 2020. We invite you to contribute to the in-memory computing conversation by submitting a speaking proposal and sharing your Ignite experiences with your peers. To

Re: question about collation with an ignite set

thanks Vlad,It doesn't look like /CollectionConfiguration/ has the ability to set the partition loss policy you specified. So the / cacheConfiguration.setCollocated(true);/ setting will locate all the elements on one cluster node? My hope was that it would keep the elements created by the node

Re: Why does CacheBasedDataSet destroy the cache it is given

Dear Courtney Robinson, let's discuss here the possible behaviour of this CacheBased Dataset closing. When designed this feature we think, that the all training parts and stuff should be deleted from Caches ad model should be serialized or exported somwhere. What is your use-case& Could you

What does all partition owners have left the grid, partition data has been lost mean?

I get the below exception on my client... #1 I rebooted the cache nodes error still continued. #2 restarted the client node error went away. #3 this seems to happen every few weeks. #4 is there some sort of timeout values and retries I can put? #5 cache operations seem to block when rebooting the

Hello! Our DEB packages are published with "all" architecture, which means they are not bound to any specific arch. Regards, -- Ilya Kasnacheev пт, 24 июл. 2020 г. в 17:31, Stanislav Lukyanov : > It should work fine. I ran Ignite on various platforms non-Intel platforms, > including arm.
