Re: Apache Ignite vs BI tools

Hello Igor, Along with ODBC driver in v1.6, is it also possible to put some video on Youtube explaining, how ODBC can be used along with few famous reporting tools in a stable manner. (something done by Gridgrain for Ignite with zeppelin integration). I think you would be already testing many repo

How REPLICATED cache is more performant comparing to PARTITIONED

I have couple of caches which are initialized per system event, and then almost stay untouched for the next 1 or 2 hours. And only reads are used. First of all is it a good use case for the REPLICATED cache? Data is small, just int to int mapping. The main question is why REPLICATED cache behaves

Re: Async workers

Hi, If the master leaves, tasks will still continue to execute. If your tasks need to be aware of the master state you should implement ComputeJobMasterLeaveAware interface. Considering the case I see two ways: 1) Put the task state into a cache where the key is task id and the value is task sta

Hi Arthi, In new release you should not run libtolize, aclocal and other autotools for every directory. Now you only should do that once in the root directory i.e. $IGNITE_HOME/platforms/cpp. Please refer to DEVNOTES.txt for detailed instructions. Best Regards, Igor On Thu, May 12, 2016 at 5:16

Re: Can't stop Ignite instance using Ignition.stopAll() or Ignition.kill() until writeBehindFlushFrequency passed

They do indeed are saved immediately, the issue is that the ignite process is not stopping until writeBehindFlushFrequency elapsed after `kill` or `stopAll` call. So, in my case for that specific IT case I have to wait 5 minutes before it completes, unless I overwrite the value of writeBehindFlushF
