Basic terms in Ignite

Hi, I am confused about few terms used often in ignite docs. Could someone please clarify them. 1. What is difference between a Server, JVM and ignite node. Can one have multiple instances of other 2, like a jvm has two nodes or a node has 2 jvms. Please explain in detail, I am very confused

Re: how to organize groups in cluster?

Can you clarify what you mean by "real-time query" in this case? Why not just start node C as a client and run a query from it? -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Cancelling a Continuous Query

Hello All, What is the correct way to cancel a Continuous Query, and make sure all the resources are used by the query are freed? I looked in the documentation and the examples, I didn't see any explicit reference to cancelling a running continuous query. Thanks, Andre -- Sent from:

Re: Basic terms in Ignite

1. You can call ignite.start() twice in the same JVM, and you get two Ignite nodes (there are some restrictions around the same cluster I don't understand). An ignite node may be a client or a server. I believe can have two client nodes in the same JVM connected to two different clusters.

Re: Cancelling a Continuous Query

Hello Andre, As mentioned in the javadoc [1], you have to call QueryCursor#close() method in order to stop receiving updates. // Create new continuous query. ContinuousQuery qry = new ContinuousQuery<>(); // Execute query and get cursor that iterates through initial

Re: Cancelling a Continuous Query

Thanks Slava! I had dropped the initial query from my continuous query, so I didn't look in that direction. You are right it is clearly stated in the docs. Future reference for others, this works even if the inital query is not specified. According to the docs: /Note that this works even

Re: ContinuousQuery - SqlFieldsQuery as InitialQuery

This makes sense, and actually that's exactly how initialQuery works. It's executed after continuous query listener is deployed, so nothing is missed, but duplicates are possible. -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: eviction performance

Hi Scott, With eagetTTL=false, each time you access an entry its TTL is automatically checked - if it is expired, the entry will be removed. It means that instead of having a separate thread waking up and removing all of the expired entries at the same time (and taking a chunk of CPU and IO for a

Re: How to achieve writethrough with ignite data streamer

Hm.. Not sore what happened exactly in your case, but cache store is never deployed via peer class loading. It's required that you have a class explicitly deployed on every node prior to start up. -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Graph Query Integration

There is no native graph support in Ignite. However, for certain use cases it might be possible to store graph data in a set of caches, and then use compute APIs [1] to do the processing. [1] https://apacheignite.readme.io/docs/compute-grid -Val -- Sent from:
