Hi, James Wang!
This is a deviation from "ideal" mean value.
So it means that this node contains less keys than "ideal" mean value for
4.7%
"Ideal" means all data distributed over cluster in uniform fashion.
In "ideal" situation this metric should be zero.
This metric is useful to detect

Hello!
Can you collect some thread dumps (Java ones, using jstack) during those 10

Hello!
Unfortunately, not much is going on in this thread dump (please use jstack
next time), but the main take away is that you seem to be using persistence.
If you are using persistence you should not expect CPU usage to hit 100%
since most of operations will be I/O-bound.
In this case you

Preferably all nodes in the cluster.

Hi,
I want to know scenarios,
1)I want to use ignite affinity key logic to keep homogeneous data in one
place, for this i created bean like
public class RowID {
private int id;
@AffinityKeyMapped
private int regid;
...
}
and configured in xml
Since we did not set the workDir explicitly it seems like the temp dir of the
tomcat was used as workDir which was of course the same directory for the
nodes running in the same tomcat.
Thanks for your help.

I created a table and inserted 9013 records in it.
The table has 17 columns and the total size of the data before import into
ignite is 282,625 bytes.
I have native persistence enabled and have 2 nodes in my cluster. Data is
replicated to both nodes.
I am using ignite 2.7.
After import into

Ignite does not enable the persistence function. The startup is to connect to
the MySql database. The Sql statement can be run in Ignite to automatically
load the data in mysql. In Ignite, select, insert, update, delete, etc., if
the data in the memory does not exist, then Automatically load data
What's the best way to access Ignite data from MS Excel? It looks like I
could use the ODBC driver but I'd like updates pushed into Excel, not
Excel polling for updates. I could use Excel-DNA and use the C# client.
Is there a better way?
I have confirmed that I am using jstack...
Jstack -J-d64 -m processId
I generated jstackInfo.txt like this.
Still have to make other orders?
That's right, currently using a regular hard drive, it seems to be stuck on
the hard drive speed.
Thank you
