How to deploy ignite service evenly across the cluster ?

Hi everyone, We use ignite's (1.7.4) service grid to deploy hundreds of (different) services in our cluster. There's a behavior we've noticed, once deploying that many services, that they tend do deploy unevenly in the cluster, that means that we can get to a point where a great number of

Re: 10X decrease in performance with Ignite 2.0.0

According to our benchmarks Ignite 2.0 is not slower for get operation. I think we need some minimal reproducer that shows the performance degradation before making any conclusions. Sergi 2017-05-12 1:10 GMT+03:00 Yakov Zhdanov : > Cross-posting to devlist. > > --Yakov >

Re: 10X decrease in performance with Ignite 2.0.0

Hi Chris, One of the most significant changes made in 2.0 was moving to an off-heap storage by default. This means that each time you do a get(), your value gets deserialized, which might be an overhead (though, I would be a bit surprised if this causes the 10x drop). Can you try setting

I've done the same thing, but just with Ignite 1.9.1 and all on one Linux machine, but that wouldn't matter. I used maven repository to get the jar files for me. I can share my dependencies of pom.xml with you. The jars are only needed on the machine where you start Ignite. Change the

Hi Humphrey, Thanks for your reply.I am trying to use *Kafka Connect* for pushing to Kafka, and from there, to Ignite, and that's why I have asked for jar files. Its okay, that I can try the Stream also. I have no idea on how to use streams, and the examples I have found were, not in a beginner

Re: 10X decrease in performance with Ignite 2.0.0

Yakov, The entire reason we use the Compute Grid is because the data employed to do the compute is large (~0.25MB) and we compute 200 at once (spread across the grid -- so ~20 per Node w/ 10 Nodes). So I do not doubt that moving the data from off-heap-memory could be large. Is there a way to try

Re: Kindly tell me where to find these jar files.

I'm not able to help you out today but Monday I can send you some code. I used the ignite Kafka streamer to get the messages from Kafka. So ignite is pulling from Kafka rather than Kafka pushing to ignite. Humphrey > On 12 May 2017, at 10:15, blasteralfred wrote: >

Chris, After looking at your code, the only slow down that may have occurred between 1.9 and 2.0 is the actual cache "get(...)" operation. As you may already know, Ignite 2.0 has moved data off-heap completely, so we do not cache data in the deserialized form any more, by default. However, you
