Any status updates on Ignite 3.0?
Greetings, The last update for Ignite 3.0 that I can find is from November of 2022, although I see the project in GitHub has had continued activity. My team is looking to start a new project using Ignite, and we were hoping to start with Ignite 3.0 since this will be a new greenfield project that we want to support for a long time into the future. Is there any timeline/roadmap for v3.0 to make it to a general release candidate? Or somewhere I can look to keep on top of its status? Or would we be better off going with the latest v2.x release and hope to migrate to v3.0 at a later date? Given the fundamental changes planned for v3.0, we were hoping to avoid having to do that. Any advice or insights would be greatly appreciated.

Internal Node and External Node
Hello, We have a use case where we want two nodes within a machine. One for internal and one for external. To be more precise, the c++ node will handle the communication and java node will handle the communication. Is there a proper way to organize the nodes? Thanks, Anthony
Re: Automatically generate Code using java reflection
Evgenii,
It also came to me if there is a similar code in C++ for the following java
code as I did not find it. If not, Does it mean I need to configure it in
xml file?
IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
BinaryConfiguration bCfg = new BinaryConfiguration();
bCfg.setCompactFooter(false);
bCfg.setNameMapper(new BinaryBasicNameMapper(true));
bCfg.setIdMapper(new BinaryBasicIdMapper(true));
bCfg.setClassNames(Collections.singleton("org.apache.ignite.examples.datagrid.CrossClass"));
igniteConfiguration.setBinaryConfiguration(bCfg);
Thank you !

Automatically generate Code using java reflection
Hello,
If I have the following java class:
public class Person implements Serializable {
/** */
private static final AtomicLong ID_GEN = new AtomicLong();
/** Person ID (indexed). */
@QuerySqlField(index = true)
public Long id;
/** Organization ID (indexed). */
@QuerySqlField(index = true)
public Long orgId;
/** First name (not-indexed). */
@QuerySqlField
public String firstName;
/** Last name (not indexed). */
@QuerySqlField
public String lastName;
/** Resume text (create LUCENE-based TEXT index for this field). */
@QueryTextField
public String resume;
/** Salary (indexed). */
@QuerySqlField(index = true)
public double salary;
/** Custom cache key to guarantee that person is always collocated with
its organization. */
private transient AffinityKey key;
And I want to create a table, I need to write the following code in
java or put them in the config file. Is it possible to generate them
automatically? As Java reflection seems can handle this?
CacheConfiguration cacheCfg = new CacheConfiguration("Person");
QueryEntity entity = new QueryEntity();
entity.setKeyType("java.lang.Long");
entity.setValueType("Person");
LinkedHashMap map = new LinkedHashMap();
map.put("orgId", "java.lang.Long");
map.put("firstName", "java.lang.String");
map.put("lastName", "java.lang.String");
map.put("Resume", "java.lang.String");
map.put("Salary", "java.lang.double");
entity.setFields(map);
entity.setIndexes(Collections.singletonList(new QueryIndex("orgId")));
List queryEntities = new ArrayList<>();
queryEntities.add(entity);
cacheCfg.setQueryEntities(queryEntities);
igniteConfiguration.setCacheConfiguration(cacheCfg);
Ignite ignite = Ignition.start(igniteConfiguration);
IgniteCache cache = ignite.getOrCreateCache("Person");
Re: Concept Question about Ignite
Evgenii ,
Have you ever happen to measure that, for cross-language marshalling, the
performance between JNI and IGNITE?

Concept Question about Ignite
Hello,
I am new to Ignite and have a few questions.
If I have two process running the following code:
Process 1:
Ignite grid = Ignition::Start(cfg);
Cache cache = grid.GetOrCreateCache("myCache");
Process 2:
Ignite grid = Ignition::Start(cfg);
Cache cache = grid.GetCache("myCache");
Will Cache be duplicated to the grid in process 2?
Thanks,
Anthony

Error and Question about communication between java node and c++ node
Hello,
I am trying to make java node and c++ node communicate with each other. I
have successfully done it between two c++ node (which is straight forward).
However, when I tried to do a put in java and a get in c++, I got some
errors. Could anyone have a look? Thanks.
Also, examples of the communication would be helpful!
I first created a node and cache in Java:
Ignite ignite = Ignition.start();
IgniteCache caches = ignite.getOrCreateCache("myCache");
And in C++:
IgniteConfiguration cfg;
Ignite grid = Ignition::Start(cfg);
// Get cache instance.
Cache caches = grid.GetCache("myCache");
Then I got the following error messages on java side:
[2020-04-02 16:10:27,131][ERROR][main][IgniteKernal] Failed to start

Re: Need help for Access Violation
Yes. I was using MSVC for both of them.
BTW, are the project odbc and thin-client in the ignite needed? I did not
build them because of some compiling issues.

Re: Need help for Access Violation
Hello,
The "usrCp" value is
NameValueType
▶ usrCp const std::string &
Seems that the "cfg.jvmClassPath" was not set properly?
I am not familiar with java environment, should i set some environmental
variable?
Thank you!

Need help for Access Violation
Hello,
I am new to ignite C++. I am using windows 10, VS community.
I keep getting Access Violation when I am trying to run the following code.
#include
#include
using namespace ignite;
int main() {
IgniteConfiguration cfg;
Ignite node = Ignition::Start(cfg);
std::cout << "node started" << std::endl;
return 0;
}
Can anyone help with that?
The error was generated from:
std::string NormalizeClasspath(const std::string& usrCp)
{
if (usrCp.empty() || *usrCp.rbegin() == ';')
return usrCp;
return usrCp + ';';
}
Following are the error messages:
Exception thrown at 0x7FFBADD635D6 (ignite.jni.dll) in Project1.exe:
0xC005: Access violation reading location 0x. occurred
Thank you !!
