Replicated cache in C++
Hi Igniters, I'd like to create a new replicated cache using C++. I suppose I'll have to use a cache template, but it's not clear, for me, how to set the name of the template... for example the meaning of '*'. Thanks, F.D.
Nodejs ThinClient and compute
Hi, is it possible to launch a "distributed compute" from a thin client of node.js? If not, do you have a workaround about it? Thanks, F.D.
Re: Nodejs cache problem.
I solved putting INTEGER_ARRAY.

Nodejs Think clint problem with byte array.
Hi, I've a problem putting in a cache entry a byte array. I've tried to use BYTE_ARRAY directly, or passing by a ComplexObjectType where one field was a BYTE_ARRAY, but it didn't work. And watching the following table: * | JavaScript type | Ignite type code | * | - | --| * | number| DOUBLE| * | boolean | BOOLEAN | * | string| STRING| * | Date | DATE | * | Timestamp*| TIMESTAMP | * | EnumItem* | ENUM | * | Decimal** | DECIMAL | * | BinaryObject* | COMPLEX_OBJECT| * | Array of number | DOUBLE_ARRAY | * | Array of boolean | BOOLEAN_ARRAY | * | Array of string | STRING_ARRAY | * | Array of Date | DATE_ARRAY| * | Array of Timestamp* | TIMESTAMP_ARRAY | * | Array of EnumItem*| ENUM_ARRAY| * | Array of Decimal**| DECIMAL_ARRAY | * | Array of BinaryObject*| OBJECT_ARRAY | * | Array of any other Object | OBJECT_ARRAY | * | Set | COLLECTION (HASH_SET) | * | Map | MAP (HASH_MAP)| * | any other Object | COMPLEX_OBJECT| seems that no mapping is present between a uint8array and a ignite type code. Can you help me? Thanks, F.D.
Re: Nodejs cache problem.
Hi Eduard,
sorry for my late reply. I've attached it to this email. But now I got a
different error message:
"Value "220" can not be cast to byte"
or
"Value "238" can not be cast to byte"
The line where I got the error is:
await cache.put(key, value);
Where value is

Description: Binary data
Nodejs cache problem.
Hi,
I'm trying to use Apache Ignite to store protobuf messages in cache, trying
to speed up our web interface.
I'm using the thin client for nodejs, and the 2.12.0 of Ignite.
I've 2 function:
async function get_cache_value(name, key)
{
const igniteClient = new IgniteClient();
let value = null;
try {
await igniteClient.connect(new IgniteClientConfiguration(ignite_ip +
':10800'));
const cache = (await igniteClient.getOrCreateCache(name)).
setKeyType(ObjectType.PRIMITIVE_TYPE.STRING).
setValueType(ObjectType.PRIMITIVE_TYPE.BYTE_ARRAY);
value = await cache.get(key);
}
catch(err) {
console.log(err.message);
}
finally {
igniteClient.disconnect();
}
return value;
}
async function put_cache_value(name, key, value)
{
const igniteClient = new IgniteClient();
try {
await igniteClient.connect(new IgniteClientConfiguration(ignite_ip +
':10800'));
const cache = await igniteClient.getCache(name).
setKeyType(ObjectType.PRIMITIVE_TYPE.STRING).
setValueType(ObjectType.PRIMITIVE_TYPE.BYTE_ARRAY);
await cache.put(key, value);
}
catch(err) {
console.log(err.message);
}
finally {
igniteClient.disconnect();
}
}
The put seems work well, but I'm not sure, but when I try to do the get I
got this error: "Type "BinaryObject" can not be cast to byte array". I'm
putting the protobuf serialized message that should be a byte array.
What's wrong?
Thanks,
F.D.
C++ Node doesnot shut down
Hi igniters, I'm using a client node in C++ to lanch several compute on a cluster, and it's working quite well, but when I try to close the node with every king of Ignition::Stop/StopAll(true/false), my client remain freezed. I'm using the 2.7.6. Do you have any suggestions? Thanks, F.D.

C++ computer delay
Hi igniters, I've a problem when I launch a sequence of about 350 compute funcions in my cluster of 10 node. I register a delay in the first launcher od about 10 sec. after that, it works smoothly. If I launch the same numbers of task on a single node, there 's no delay. It seems like a problem in the discovery process of the whole grid. Do you have any ideas? Thanks, F. D.

Re: Ignite and dynamic linking
Hi Igor,
thanks for your reply, I've added this code:
Snippet
void Ignition::DestroyJVM()
{
factoryLock.Enter();
JniErrorInfo jniErr;
SharedPointer ctx(JniContext::Create(0, 0,
JniHandlers(), &jniErr));
IgniteError err;
IgniteError::SetError(jniErr.code, jniErr.errCls, jniErr.errMsg, err);
if(err.GetCode() == IgniteError::IGNITE_SUCCESS)
ctx.Get()->DestroyJvm();
factoryLock.Leave();
}
And call it before the FreeLibrary(), now when I call the start I got a
unknow error. Any ideas?
Thanks,
F.D.

Ignite and dynamic linking
Hi Igniters, I'm trying to use Ignite in a dll (using c++) that is dinamically loaded. I wrapped the method start/end/... bihind a "c" pure interface that I export. It works quite well. I can call the LoadLibrary and start a Ignite node. I can stop it and restart it again smoothly. I've the problem when I LoadLibrary and then I call FreeLibrary (and until here it works), but when I try to LoadLibrary again and to start the node, I get the error: Failed to initialize JVM* [errCls=, errMsg=JVM already created.]* Do you any ideas why I got this error?

Re: Ignite .NET in docker (linux)?
I've done some further steps.
now the docker file is:
FROM microsoft/dotnet:2.1-sdk
ENV http_proxy='http://10.0.75.1:3128'
ENV https_proxy='https://10.0.75.1:3128'
WORKDIR /app
RUN apt update && apt install default-jdk -y --no-install-recommends
COPY *.csproj ./
COPY nuget.config ./
RUN dotnet restore --configfile nuget.config
COPY . ./
ENTRYPOINT ["dotnet", "run"]
I've added some env variables to permits to the apt to install the jdk. But
now I've a problem with nuget.
I added a configuration file:
http://10.0.75.1:3128"; />
But I got this error message:

Re: Ignite .NET in docker (linux)?
Ok, so your idea is to build an image starting from Microsoft .NET image.
Then you add the java jdk, and make a c# project that launch the ignite
node, is it right?
Can you clarify to me these lines:
...
RUN dotnet restore
...
ENTRYPOINT ["dotnet", "run"]

Re: Ignite .NET in docker (linux)?
Thanks for your support, but I need more informations. Let me try to give
you more details:
I've launched a ignite node on docker with this command:
docker run -it --rm --name ignite --net=host apacheignite/ignite
Then I try to connect to my dotnet client with this configuration:
Snippet
Ignite = Ignition.Start(new IgniteConfiguration
{
Localhost = Dns.GetHostName(),
ClientMode = true,
DiscoverySpi = new TcpDiscoverySpi
{
IpFinder = new TcpDiscoveryMulticastIpFinder
{
LocalAddress = "AAA.BBB.CCC.DDD"
},
SocketTimeout = TimeSpan.FromSeconds(0.3)
},
IncludedEventTypes = EventType.CacheAll,
});
But I got this errors on the server node:
[10:36:28,512][SEVERE][sys-stripe-2-#3][query] CacheEntryEventFilter
failed: class o.a.i.IgniteException: Platforms are not available
[nodeId=861e0f56-6a8b-4ff9-9ea0-a6e5c4d3126b] (Use
Apache.Ignite.Core.Ignition.Start() or Apache.Ignite.exe to start
Ignite.NET nodes; ignite::Ignition::Start() or ignite.exe to start Ignite
C++ nodes).
I suppose I should start the .NET Ignite (the thing that I did when I
didn't use docker). Can you help me?
Thanks,
F.D.

Re: How works an ignite node?
Hi Eduard, I'm looking for maximum throughput , I thought so, but I found that I've the best performance with the same number of ignite instance as the cores. I've more than 8000 distributed closures that I want to execute on my ignite node. At the beginning of the execution the CPU is at 100% of utilizzation, but after about a minute, it collapses to around 20%. Consider that the execution spent 18 min with 1 node and 3 min with 16 nodes (my server has 16 core). Any ideas?

Hi igniters, I'm testing my client/server nodes using C++ distributed closures. So, I've a question or you: on my server, where I launched my server node, how many instance of server I've to launch? One for each physical core? What's the rule for an optimal performance? Thanks, F.D.
C++ client only
Hi Igniters, I've my client (C++) and I want to send my computations (distritubuted closures) on a server. I want to prevent my client from participating in the calculation. I've inserted in the client configuration file this line: but I continue to see that part of the distributed closures are continuing to be executed on the client side. Is there any other configuration to do? Thanks, F.D.

Re: Distributed closure with buffer of binary data
Ok, but I think it's the same like WriteArray. For the moment I solved in a different way,using a encode/decode functions.

Distributed closure with buffer of binary data
Hello Igniters, My distributed closures work perfectly when the inputs are strings, but when I try to pass a buffer of bytes I got an error. The buffer of bytes arrives to me in a std::string but when I to use BinaryWriter::WriteString the string is truncated (ok, it was predictable). The question is there a method of BinaryWriter/BinaryReader to handles with buffer of char? (I found WriteArray, but I've to pass char by char). Thanks, F.D.
Contribution on Ignite
Hi Igniters, I want to thank you because, my distrubuted closures are working perfectly! Now I'd like to do a step further. What I really need are the API for Service in C++. I already know that are missing, and maybe C++ is not your first thought. So, I'd like to try to contribute to the project trying to devel this part. But I need your help because I've no idea where to start. Thanks, F.D.

My fault!!! I modified the code in this way:
static void Write(BinaryWriter& writer, const Calculation& obj)
{
writer.WriteBool("local_log", obj.local_log_);
writer.WriteString("service_name", obj.service_name_);
auto sa_writer = writer.WriteStringArray("input");

sa_writer.Write(s);
sa_writer.Close();

static void Read(BinaryReader& reader, Calculation& dst)

dst.service_name_ = reader.ReadString("service_name");
auto sa_reader = reader.ReadStringArray("input");
while(sa_reader.HasNext())
dst.input_.push_back(sa_reader.GetNext());
}
and now work perfectly!
Sorry and thanks again!

Distribute closures error: "Operation cannot be performed in raw mode."
Hi Igniters,
finally, I've compiled my code and run my test. But after I call my closure
I got this errors: "Operation cannot be performed in raw mode.", and
unfortunally I've no idea what it does mean.
This is the code of call:
IgniteConfiguration cfg;
std::string home = getenv("IGNITE_HOME");
fs::path cfg_path = fs::path(home) / "platforms" / "cpp" /
"client_config.xml";
cfg.springCfgPath = cfg_path.string();
ignite = Ignition::Start(cfg);
IgniteBinding binding = ignite.GetBinding();
binding.RegisterComputeFunc();
Compute compute = ignite.GetCompute();
[...]
Calculation functor(name, args, false);
auto fut = compute.CallAsync(functor);
[...]
And Calculation is:
class CalculationEngineIgniteServer: public
ignite::compute::ComputeFunc
{
friend struct ignite::binary::BinaryType;
public:
CalculationEngineIgniteServer(
) = default;
CalculationEngineIgniteServer(
const std::string &name,
const std::vector &input,
bool localLog
);
virtual std::string Call();
private:
std::string name_;
bool local_log_;
std::vector input_;
};
Then I defined BinaryType for Calculation and for std::vector.
I don't understand where I miss.
Thanks,
F.D.

Hi Pavel, Yes, but thin client cannot perform continuous query. Maybe is there an alternative way to be notified when a cache change?
