Re: How is igfs:// URL resolved?

[Denis Magda]

Kobe,

In my understanding everything looks fine in your approach.

Summarizing the execution flow will look like this:
- client sends a request "http:/some.host.com/get/myigfs/data/content.gif";
- server receives the request and gets IGFS file system name (myigfs) 
and a path to a file to return (data/content.gif) from it;
- server code gets a reference to IgniteFIleSystem named "myigfs" and 
opens IgfsInputStream to the content path;
- reads data from IgfsInputStream and writes it back to response's 
OutputStream

into a URL that the client can consume.

The only thought I have is that I could  open IgfsInputStream and stream it
into HttpConnection OutputStream after setting the appropriate content-type
like so:



// Open input stream to the image in IGFS ...
  IgniteFileSystem fs = ignite.fileSystem("myigfs");
 IgfsPath myImage = new IgfsPath("/data/content.gif");
   IgfsInputStream inps = fs.open(myImage);

byte[] buf = new byte[4096];
int len = -1;

// Read from IGFS input stream and stuff into servlet response output
stream
while ((len = inStream.read(buf)) != -1) {
 outStream.write(buf, 0, len);
}

outStream.flush();
outStream.close();

Is there a better way?

thanks again for your assistance.

isManagementEnabled vs isStatisticsEnabled.

[vinshar]

Hi,

I see that Ignite registers same bean in case if any of the above flags are
true. Bean is of type
/"org.apache.ignite.internal.processors.cache.CacheMetricsMXBeanImpl"/. This
/CacheMetricsMXBeanImplclass /implements /CacheMetricsMXBean / which extends
below both interfaces defined in JSR107.
/"import javax.cache.management.CacheMXBean"
"import javax.cache.management.CacheStatisticsMXBean"/

So it seems like setting any of isManagementEnabled and isStatisticsEnabled
flags will do the same thing.
Is there anything where setting one flag is different from setting the other
one? 

Regards,
Vinay

Hi there,

I'm a bit confused about the purpose and usage of this property. What is being 
shared with who? What are the consequences of setting the property to true or 
false? Under what circumstances would one want to set it to either true or 
false? Does one care at all?

Re: Ignite "bugs" ?

[Matt Hoffman]

No, I understand that you can't control what other projects do, and it's
not always possible to fix bugs at their source.

I imagine the best thing for Ignite to do in this case is to iterate
through the properties and just ignore anything that isn't a String. It
wouldn't be meaningful when deserialized anyway.

Ignite "bugs" ?

[Yann BLAZART]

Hello everybody.

I'm currently evaluation Ignite vs Hazelcast on a poc.

I'm facing some issues.
I'm coding some integration/unit test using the ApplicationComposer of TomEE 
7.0.0. I have no problem with Hazelcast on it.


* The first one is when I'm start Ignite in the applicationComposer 
(with a CDI @Produces), Ignite complain about some System.properties that are 
not String :


it try to "serialize" System.properties by using 
System.getProperties().store(new PrintWriter(sw));



In fact, TomEE (as other framework like hibernate) use System.properties to 
store prop objects.



So I made something to remove this properties before Ignite start and recover 
its after. Well. Pehraps it will be nice to change the way to "serialize" 
System.properties.



* The second problem is strange, very strange. If I'm making a call to 
Ignite.start in @Before or using a @Inject in the test class (that use the 
@Produce that make the call to start(), everything is ok. But if the start is 
called in the @Test method (so after ApplicationComposer has made some things), 
Ignite is "locked".

o   Precisely in IgniteKernel.java:917  :



// Start discovery manager last to make sure that grid is fully initialized.
startManager(discoMgr);



The call to  this method never exit.



Any idea to help me to understand ? Anybody has tried to use Ignite with EE or 
CDI ?

Re: putting to cache as generic object

[Anton Vinogradov]

Hello Ambha,

Seem you need to use BinaryMarshaller (
https://apacheignite.readme.io/docs/binary-marshaller)
In this case you can create objects using binary builder and read field's
values using BinaryObject (Reflection like mechanism)

Re: Setting both offHeapMaxMemory and cacheStoreFactory

[Denis Magda]

Hi,

Please see my answers inline

On 1/13/2016 10:44 AM, Ambha wrote:

I have a few doubts on off heap cache configuration
1. Is it possible to set both off-heap and cache store with write behind
mode for a cache?
The configuration looks like:









 




   
  


Yes, it's possible to use off-heap space for a cache and sync data to a 
storage in either write-through or write-behind mode.


Actually, cache store is not bound to any cache memory mode (on-heap, 
off-heap, swap) where cache data can reside.

Please refer to [1] to get more details.


2. from which place (onheap or offheap or both) the cached objects are
written to cache store (MySQL above) if write behind is enabled?
If write-behind is enabled cache objects that must be synced to a 
storage are queued up in the write-behind store implementation and 
flushed up later.
There is no difference whether the objects are actually stored - in 
on-heap or off-heap.

You can find more details on write-behind store here [2].


3. What will happen to a new item to be placed in cache when the size (both
onheap and offheap) has already exceeded the limit?
You will face with out of memory situation unless you configured an 
eviction policy that moves data to swap. [3]

Re: Cache.put latencies high

[Dmitriy Setrakyan]

This is usually a problem with one-threaded benchmarks.

1. You should add a warm up step, i.e. have your system work for about a
minute before starting measuring.

2. You should decide whether your application will be single-threaded or
multi-threaded. If it is multi-threaded, then your test should also be
multi-threaded.

3. And finally you should verify that network works well in your
environment. Do you have 10G ethernet?

Re: SQL Query returns no value if different values put twice with same key

[Denis Magda]

Hi Vinay,

To overcome the exception you have to add the class to server's node 
classpath as well.
If you don't want to have classes in server nodes classpath you can 
start using Ignite 1.5.0 release that has binary objects[1] in its 
features list.

Hi Val,

You are right. I totally missed the point that i changed id of 2nd 
object.


There was no system in my network and visor also showed nothing. I 
will restart system and try again.


How about class not found exception. Am i doing something wrong in 
this code which should cause this exception on server node?

Vinay

Re: How is igfs:// URL resolved?

[Denis Magda]

Hi Kobe,

There is no an example for your specific use case.
However your understanding is correct on how this should be implemented.

This is exactly what I had in mind when was going the suggestions in the 
previous reply


   IgniteFileSystem fs = ignite.fileSystem("myigfs");

// Image path.
IgfsPath workDir = new IgfsPath("/data/content.gif");

Hi Kobe,

If I understood you task properly you want to map a path portion of an
HTTP request to an IGFS path.

If this is your case then I would suggest doing the following:
- create a Web application that is running in a Tomcat container;
- the application will use Ignite in the embedded mode (start an Ignite
node from the app code);
- process incoming HTTP requests as usual extracting the path part from a
request;
- take instance of Igfs from previously started Ignite node and pass the
path and content to it. Refer to IgfsExample that is a part of Ignite
bundle/sources for more details.

Regards,
Denis

Denis,

I went through the IGFS examples and did not quite see what I wanted. My
problem is simply this:
I am generating content into a file in IGFS that needs to be displayed on
the browser. If the content (on the server) were in file
webapps/myapp/content.gif I would return the URL
   http:///myapp/content.gif
to the browser to the content may be rendered on the browser.

Since my content is in IGFS, what would be the file:// URL of a file in
(embedded) IGFS instance
"myigfs" in path /data/content.gif as shown below?


IgniteFileSystem fs = ignite.fileSystem("myigfs");

 // Image path.
 IgfsPath workDir = new IgfsPath("/data/content.gif");

Thanx,

kobe

Is it also possible that we create a branch with this fix and provide it
