Memeory Leaks of Swapspace

Hi devs. I am running ignite github master branch. My case is simple, use OFF_HEAP and enable swap. For I know this bug (https://issues.apache.org/jira/browse/IGNITE-3840) isn't merge into the master. So I disable any expiry policy. After running for a while, I checked the memory usage of

Re: BinaryObject pros/cons

Cross-posting this to dev list. Vladimir, To be honest, I don't see much difference between null values for objects and zero values for primitives. From BinaryObject semantics standpoint, both are default values for corresponding types. These values will be returned from the BinaryObject.field()

Re: Any plan for a book on Apache Ignite

Prachi, Would you add a reference to this book [1] under “Community”->”Resources” section? It contains useful and valuable information a lot of guys who will start working with Ignite will benefit from. [1] https://leanpub.com/ignite — Denis > On Sep 18, 2016,

Simply because it makes Ignite Spark integration unreliable as well. — Denis > On Oct 27, 2016, at 12:02 PM, Dmitriy Setrakyan wrote: > > Why not make it mandatory only with "ignite-spark" dependency? > > On Thu, Oct 27, 2016 at 11:53 AM, Denis Magda

Re: Making Ignite shmem library optional

Dmitry, I don't think it's possible. Shared mode is supposed to help in the standalone mode, but in this mode server nodes are not required to have ignite-spark dependency. They just store data in caches. -Val On Thu, Oct 27, 2016 at 12:02 PM, Dmitriy Setrakyan wrote: >

Re: Making Ignite shmem library optional

Absolutely agree. This functionality is unreliable right now and at the very least it should be switched off by default as soon as possible. Going forward, it should be either fixed or removed, because it's just a broken piece of code. -Val On Thu, Oct 27, 2016 at 11:53 AM, Denis Magda

Why not make it mandatory only with "ignite-spark" dependency? On Thu, Oct 27, 2016 at 11:53 AM, Denis Magda wrote: > Igniters, > > Presently, if someone starts up a cluster and has at least two nodes > running on a single Unix machine then those nodes will be communicating

Making Ignite shmem library optional

Igniters, Presently, if someone starts up a cluster and has at least two nodes running on a single Unix machine then those nodes will be communicating over the shared memory (shmem) by default. This approach sounds absolutely reasonable for me but the shmem library is not ideal at the moment.

Re: Apache Ignite 1.8 Release

Hi, I have added some tests for ODBC that include DML - they are passing on the DML branch. I've also made some changes to ODBC for it to work better with PDO. Some of them are already merged, other will be merged once DML is ready. Ksenia currently works on testing PDO with our ODBC driver very

Re: IGNITE-4088

I would prefer that we would declare all exceptions thrown at method signature level, just so they appear in Javadoc and we can document them. So, to answer your question, please fix other methods, if you don't mind. D. On Thu, Oct 27, 2016 at 1:55 AM, Константин Дудков wrote: >

Do we know the status of the DML support? It looks like Alexander Paschenko is working on it. Alexander, can you provide an update? On Thu, Oct 27, 2016 at 9:13 AM, Pavel Tupitsyn wrote: > Also I'd like to include at least some of .NET Usability Improvements ( >

Re: Create separate thread pool for query execution

Andrey, I am not aware of any serious issues with thread pools configuration. For cache pool ("system pool") [cores * 2] makes sense, because usually cache operations are fast and small, but contains blocking operations around (e.g. moving task from blocking queue to the thread). Sometimes [cores

Re: IGNITE-4088

Dmitriy, Thank you for your answer. As far as I see, other methods f.e. createCache throw CacheException too, but have nothing about that fact in signature or javadoc. Should we review all API methods to have same unchecked exception documenting rules? 27.10.2016, 08:41, "Dmitriy Setrakyan"
