Properly Immutable Keys/values with Binary objects ?

Some of our keys/values are properly immutable Java objects (with final), and it appears that the java Serialization is the only way these can be serialized. Looking at BinaryClassDescriptor#newInstance it appears a no-args constructor is the only supported method, and the BinaryConfiguration does

Re: Ignite C++ ScanQuery slower than Jav ScanQuery by 2x always

Thats great !!!. I am sure that this will improve performance as this is one of the hottest method, and as I mentioned earlier this happens in Java too. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-C-ScanQuery-slower-than-Jav-ScanQuery-by-2x-always-tp60

In the code I tried reproduce you issue. I ran code in 2 IDEA sessions, the ignite work correctly without any exception. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/IGFS-Semaphore-Write-file-concurrently-from-several-nodes-tp6009p6080.html Sent from the Apach

Re: Ignite C++ ScanQuery slower than Jav ScanQuery by 2x always

I have took a closer look on EnsureEnoughData() issues and seem to be found the roots of it. I've filed a ticket for this issue - [1]. [1] - IGNITE-3416: CPP: Review and optimize serialization and deserialization. Best Regards, Igor On Mon, Jul

Re: Starting H2 Debug Console On Remote Server

Ok. I understand. I need to start the ignite server instance on my local machine to view the h2 debug console. I have been experiencing web session timeout on the h2 debug console after which I see the h2 login screen. If I specify the db name in the jdbc url as the random id that was earlier gene

Re: Ignite C++ ScanQuery slower than Jav ScanQuery by 2x always

Igor, Many thanks. For me that __scrt_common_main_seh looked starnge due to complete unfamiliarity with the code. That EnsureEnoughData is so hot bugs me too, I have seen it in Java also though. The BinaryWriter should help definitely, but i am struggling with it due to some weird problems.

Re: Iterating through a BinaryObject cache fails

Ok. Thanks for sharing the internals. By specifying the withKeepBinary flag, I was able to iterate through the cache and add or drop fields from a BinaryObject at runtime. This was the original purpose of iterating through the cache. The changes (of adding and/or dropping a field) made to the cac

Re: Error while loading data into cache with BinaryObject as key field

1. The strange part is even when the binary objects are created with different type names (different for key BinaryObject and for value BinaryObject), I am able to query the field that is the part of the key BinaryObject by specifying the valuetype 2. By "binary type descriptor" I understand that

Re: Iterating through a BinaryObject cache fails

Hi, You should always use withKeepBinary if you plan to work with a cache containing BInaryObject key or value (including queries). The flag is used internally to prevent deserialization from binary representation to actual class instance. So the answers are: 1. yes if you want to load binary ob

Re: [IGFS][Semaphore] Write file concurrently from several nodes

Hi Andrey, Thanks for replying. It seems the code you posted on github is quite similar to the one I already posted in this thread (except for the Thread.sleep and the outputwriter used for writing the file). What exactly would you need for me to add? Greetings, Cristi -- View this message in

Re: Error while loading data into cache with BinaryObject as key field

Hi, 1. I see nothing strange here. Please explain in more details. 2. Because query engine uses binary type descriptor to update SQL indices for incoming data. 2016-07-03 20:16 GMT+03:00 pragmaticbigdata : > Thanks for pinpointing the issue. The issue got resolved after setting a > custom key

Re: .net configure sql query with c# code, when execute query, return empty set

Hi, You have to use Ignite Binary Serialization to enable SQL queries [1]. To do that, remove [Serializable] attribute and register Employee class in the configuration: var cfg = new IgniteConfiguration { CacheConfiguration = new[] {

Re: Ignite C++ ScanQuery slower than Jav ScanQuery by 2x always

Hi, It is nothing strange for the __scrt_common_main_seh to be a hot spot as it is C++ program entry point. I took a look on the profiling results you provided and it seems like a lot of time is spent in serialization/deserialization methods. The most hot method is surprisingly InputStream::Ensur
