Utility to check size of entries in off-heap

Hi, I have turned on off-heap cache memory settings while trying to load close to 300 million records in to the ignite server cluster. When I had the cache use java heap alone, I was able to get the cache size details and number of records using "ignitevisorcmd.sh". Once I enabled off-heap memory

Node.js features

I see some activity on node.js integration as part of 1.6 release. Is there any plan to support continuous queries? Also, will there be support for messaging (queue) too? -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Node-js-features-tp2441.html Sent from the A

Re: How asynchronous cache is implemented

Thanks Val. I suppose the communicate queue is an in-memory queue? What is the class name of that communication queue? Thanks again. Antonio. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/How-asynchronous-cache-is-implemented-tp2399p2438.html Sent from the A

Re: Point to point messaging with Ignite

Yep, although this is not a message-oriented pattern, but rather a RPC call and an implementation of the "Command Message" integration pattern. I was under the impression that the OP wanted to send message/data across, not necessarily invoke a discrete action per message type... @kcheng – when I

Re: Distributed queue problem with peerClassLoading enabled

Hello Denis, Thanks a lot for your reply! Concerning point 2: does it mean that "peerClassLoading" simply does not work in 1.5? It used to work (partially) in 1.4 (details described earlier in the message thread). Cheers, -Mateusz On Thu, Jan 7, 2016 at 1:38 PM, Denis Magda wrote: > Hi Mateu

Re: Distributed queue problem with peerClassLoading enabled

Hi Mateusz, 1. It seems that distributed cache is still *not* available in PRIVATE/ISOLATED modes. Is this correct? Right, it hasn't been fixed yet. I've just followed up the related discussion on the dev list. Please follow it to see the most up-to-date information http://apache-ignite-devel

Re: Point to point messaging with Ignite

Ah, you could also use distributed locks to represent ownership, and events to get informed when a node leaves, without blocking a thread indefinitely until the lock is released. There are many possibilities. *Raúl Kripalani* PMC & Committer @ Apache Ignite, Apache Camel | Integration, Big Data an
