Re: Error while running query against Ignite Server Node
Hi,
I am running 3 instances of ignite per machine(total 3 machines). Data is
inserted in partitioned cache continuously and I am running query against
this cache. After query I am getting above error. Is there any way I can
make topology stable before querying data? For example, how can I query data
up to certain snapshot of cache when data is continuously getting added and
I am querying data to avoid this error(As this error only occurs during run
time query against data i.e. when cache is getting populated and not when
cache is completely loaded)
Thanks.

Alper,
Did you lose any data or you just got the same error in log?
You could get the same error when minor version of topology was changed
during DataStreamer's flushing

Hi Nikolai,
By saying:
> This exception means that in during data streaming, topology was changed.
Do you mean major topology or minor topology? And also what is minor
topology? We have encountered same issue without no change in topology
version no new nodes added or left but with different minorTopVer.

Hi,
It's looks that you have long gc pause in your application. Did you see in
logs any message related with changing topology (node fail, node left, node
join and etc)? Could you enable gc logs and check it (for example
-Xloggc:./gc.log -XX:+PrintGCDetails -verbose:gc)?
