Hi dmagda,
When I insert many records (~ 10 or 20 million) to the same table and try
to drop table or delete records from the table, nodes are restarting, the
restarts happens In the middle of drop or delete operation.
According to the logs the cause for restart looks like OOM in the data
region.
Hi Deepak,
Thank you for your interest in Apache Ignite.
Have you ever considered the applicability of usage of Apache Ignite in
Apache OFBiz. Would it be useful as scalable storage? As storage option?
Maybe we can think about some integration of these two projects. WDYT?
One more thing, do you
Yes, Dmitry.
Recently I did one small PoC for integrating OFBiz with Ignite in an
attempt to improve the performance of OFBiz in large data fetching. I tried
with both in-memory and persistence mode and the initial results of this
PoC were awesome.
Regarding static code inspections, as of now, I
Hi Pavel,
I have some queries related to cache groups ,if you help it will be useful
for us.
*instead of one cache per company, use one cache group per company.
*
1.What is the performance impact
=>Is there any number of cache group limitations?
here cachegroups proportional to tenants
2.
Please accept my sincere apologies for the typo in your name, Dmitriy.
Thanks & Regards

Hi Evgenii,
Even with *where condition*, I am getting the same error.
I have some use case where I can't collocate tables data, as Ignite doc
says non-collocated distributed join or cross join is supported in Ignite I
am trying to use that but getting this exception when I create tables in

Too many things come into play here, the only way to know is to test both
approaches on your use case.
By the way, do you have the same table set for every tenant?
It may be beneficial to group caches not by tenant, but by data size and
type.

Hi Shiva,
Could you please check that ignite-rest-http library is added to OPTION_LIBS

Yes right now,we have same table schema for each tenant

Hi All,
did anyone have an cloud formation example for deploying Apache Ignite on
AWS or steps to deploy or some successful deployment of Ignite onto AWS.
this below blog has missing artifacts so not working.

Hello!
Unfortunately it's hard to say, I'm afraid you will have to debug it or
break down your tasks until you see what step causes this issue.

Hi Community,
this doesn't launch a multinode ignite cluster am I right? it just launches
a single node ignite cluster on one ec2 instance.

Hello!
I recommend keeping all pools at something like 4.
Ignite clients can run a lot of operations (they can do compute, they use
cache store when load is transactional, they run visor tasks, etc) so it's
better to not zero out all pools outright.

Hello!
If you have a lot of these classes, this may mean you have some problems
with marshalling: Ignite considers a lot of what you have in your program
different types. This may cause issues.
Those files are very small so I don't think it should cause issues. Client

This is an interesting situation to consider.
Have you tried *SELECT* * *FROM* City *AS* c *join* (SELECT * FROM Person)

Otherwise, I don't think we support joins without conditions, unless most
of tables are replicated.

Hello!
"Failed to read data from remote connection" in absence of other errors
points to potential network problems. Maybe you have short idle timeout for
TCP connections? Maybe they get blockaded?

Thanks for the response Ilya.
So from a sequence of events perspective, first the logs show "Partition states
validation has failed for group" for many minutes. And only after that we see
the "Failed to read data from remote connection" caused by
"java.nio.channels.ClosedChannelException". So
Hello!
This would happen if you have any non-inlined indexes. You need to load a
lot of pages for every write and you are running out of offheap.
4G is a tiny offheap.

Hi Deepak,
No problem, since both options are understandable :)
I am happy to hear from you about good results you've got in this PoC.
Have you written a blog or article on this subject? I would be happy to
repost it.
Warm regards,

Hello Sri,
You’re right, you need to start several aws instances to create a
distributed cluster if you follow the guide below. Ignite configuration for
all the nodes/instances has to have a properly configured IPFinder. You can
use a static IP finder if IPs are know in advance or AWS IPfinder if
looks complex and hard to get it right, it would be nice if Ignite
community builds one working cloud formation template to launch ignite
cluster and in the cloud formation template output a JDBC connection for
connecting ignite cluster which would be awesome.
Many would leverage this stack to bui
