Hello,
1-I have two servers one on local and other on remote host.
Both nodes are added to Baseline Topology.
2-I have started the cache in replicated mode on both the server nodes.
The data is replicated on both nodes properly however when both nodes are
running the size of data in node shown is d
Veena, thanks for the ticket! We’ll take care of it.

If Ignite can hold all the records in memory it won't be reading pages from
disk (the page replacement). Thus, it's expected that the 12GB performs
better than the 5GB case.
Btw, are you planning to reload the whole data set into Ignite on potential
cluster restarts? Each node loses a subset of th
Hi, I am new to ignite. I have a requirement and I don't know how to achieve
it through Ignite.
My usecase:
Suppose if I have 3 servers, one among them will act as a leader and will
co-ordinate all the internal service requests.
The requests should get executed either in the same server(leader) o
Hi Denis,
We did a test, in the same environment (8G RAM, 10G swap partition) and
the same configuration (2G Heap, enable persistence, data volume is
about 6G), the only difference is that the maxSize size is different,
which is configured as 5G and 12G respectively. We found that the

Ignite swapping is based on the swapping mechanism of the OS. So, you
shouldn’t see any difference if enable the OS one directly some way.
Generally, you should not use swapping of any form as a permanent
persistence layer due to the performance penalty. Once the swapping kicks
in, you should scal
Hello Igniters,
I would like to share with you the video recording[1] of our presentation
from the last Ignite Virtual Meetup. Although our use case might sound a
bit extraordinary, we are extremely satisfied with our decision to use
Ignite for it.
Thanks, Branimir

I can't see any difference with or without an index. with 1.000.000 rows it

Our target size will be 300.000.000 rows easily.

Hello,
Is there a Change Data Capture (CDC) feature in plans to make it possible
to stream cache updates to Kafka for example?
I've found the Continuous Queries feature, but it's not clear to me whether
it's possible to use it for implementation. What's missing it seems is

Hello,
In my case, 'cache.ignite.com' is a L4 and the port is 80.
cache.ignite.com(ex. 41.1.166.123) will be connect Ignite Server.(ex.
42.1.129.123:47500, 42.1.129.123:47501 ...)
Is it possible? or should I define port for connect to Ignite Server.
I will waiting for reply!
Thank u so much!
The cache.query() starts to block when ignite server nodes are being
restarted and there's no baseline topology yet. The server nodes do not
block. It's the client that blocks.
The dumpfiles are of the server nodes. The screen shot is from the client
app using your kit profiler on the client side
Hello all, I'm trying to upgrade an existing cluster from 2.7.0 to 2.8.1, and
am following the upgrade procedure outlined in the Ignite documentation. I'm
noticing new warnings I haven't seen before from my 2.8.1 clients, and am
not sure how to get rid of them, or how important they are to fix.

Hi,
We retested and found that if we configured swapPath, as the amount of
data increased, the write speed was actually slower and slower. If the
amount of data is large, on average, it is much slower than the scenario
where native persistence is enabled and wal is disabled.
In this way, the

However m requirements are

Hello!
You can use control.sh. It can look up nodes as well as add them to
baseline.
Unfortunately I did not see your commands so I can't know for sure. I'm not
sure that auto-adjust will work for nodes added prior to enabling it.

It should work. If port is not specified, discoveryPort or default port
(47500) will be used.
Hostnames are supported all right.

But we are creating cache node in off heap memory right?
Then why is it showing double value in "On heap"?
Is it only showing double size as On heap or it will actually allocate that
much memory?
