Re: Ignite Services: How to preserve value of Local variables ?

Val. In real use-case, all the initialization are done in the *init* block. Due to the above mentioned behavior, I want to deploy the services locally / manually after initialization. The suggested approach to deploy a service only in the local node is not working. Do you have any alternate solut

To achieve this, can you provide me config changes I need to make in my config files as well as my code that star

Re: Failed to wait for initial partition map exchange

hi Val, seems that when there's assertion or OOM in one node, it doesn't exit, right? so it still sends heartbeat to others, then the whole cluster are waiting for it to recover (hanging). Is there any easy way to let one node restart immediately when encounter unrecoverable errors, like OOM or s

Re: Implementing a distributed crawler

As I already mentioned, I would use compute grid for this. As for the back pressure, you can limit the number of jobs executed at the same time and define different scheduling strategies [1]. The queue just looks like an unnecessary piece here. [1] https://apacheignite.readme.io/docs/job-schedulin

Hi Val, thanks for you help. I really like the aspects of the blocking-queue to provide natural "back pressure", but if performance becomes a real problem here, can you suggest an alternative approach? -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Implementing-

Hi Kamal, This issue is related to this one: https://issues.apache.org/jira/browse/IGNITE-3392. Current service deployment process is asynchronous, so if it takes a lot of time to deploy it, you can get these exceptions in the logs. Note that they actually do not break anything, everything becomes

Re: transaction not timing out

Yes, prepare phase happens within the commit() and the commit phase start only after prepare is finished. The commit phase updates the data which includes write-through to the database. So if commit takes a lot of time due to issues with the database, we can't rollback without causing data inconsi

Hi VM, This sounds like a good use case for Compute Grid [1]. It will allow you to do parallel processing with proper failover and load balancing. The issue with the distributed queue is that any operation is actually the update of a single entry in cache, so this will be a single point of conten
