Hello Val,
I now put the stream visitor code in a different model and packaged it in a
different jar with dependencies.
Interestingly, when I ran the program again, the server node has weird error
messages.
The FileConnector is a class in the client jar. Why would the service needs

I'm having following error when starting Ignite server node

I used REST API put command and was able to valid the number of entries using
REST size command as well as visor.
However when I use JDBC to connect to ignite directly, the select count(*)
return 0 rows.
Has anyone tried that before? Is it a bug?

Mikhail, found out some process is using 8080 and ignite used 8081 instead.
Good catch!
On the other hand, does Ignite REST support batch request? And if not, how
good is the performance of REST comparing to Java API?

Mikhail, which version of ignite did you use? Was it 2.0.0?
I used on 1.8 before and it worked fine, but not on 2.0
Btw, does Ignite REST support batch request? And if not, how good is the
performance of REST comparing to Java API?
Thank you for helping!

Hello,
When is CacheStoreAdapter sessionEnd method called?
I implemented a persistent store with a overriding sessionEnd mothod like
this.
@Override
public void sessionEnd(boolean commit) {
Connection conn = null;
System.out.println("CALL me ");
Thank you! I'll give it a try.
