Need your advice for using DataStreamer

Hi igniters, My situation is like below. There are 3000+ message senders outside. They will send message per 0.1 sec and the sequence of message have to be kept per each sender. So I made a cache to buffer all messages then put all message into the cache using DataStreamer. But when I getting

Re: Node discovery behind NAT

Hi Valentin, Well, we can certainly work with this setup. Not ideal but usable ;) Will look into doing something about UPnP to see if I can make the whole think a bit more dynamic. Thank you for your help! Best regards, Petar On Thu, Feb 11, 2016 at 8:48 PM, vkulichenko

Re: Externalizable in cache

Hello Alexey, This is actually not real code but just extracted part for test. That's why it looks incorrect. And I've already captured infinite loop because of 0 being returned. And imagine use case when I need to read until end of stream. So question is why 0 is returned but not -1 (according

Alexey, is this something that Ignite could prevent automatically? On Mon, Feb 15, 2016 at 10:17 AM, Alexey Goncharuk < alexey.goncha...@gmail.com> wrote: > A little correction: in this particular case inputStream does return 0 > which leads to an infinite loop, however, generally this may be

Re: Externalizable in cache

A little correction: in this particular case inputStream does return 0 which leads to an infinite loop, however, generally this may be not the case, so the implementation should not read beyond object boundary anyways.

Re: Externalizable in cache

Hello Myron, Your implementation of Externalizable interface is incorrect. The number of bytes that can be read from the object input stream passed to the readExternal() method is not limited, so you need to make sure that you do not read more bytes than the number of bytes written. The correct

Re: binding exception?

This exception is thrown on Jetty start, however, it is not critical and just signals that rest server cannot be started on desired port. To fix this please set Jetty logger threshold to ERROR. btw, Vladimir, can we fix this in default jdk logger configuration? --Yakov 2016-02-15 16:02

Re: SQL join Query

Hi Shaomin, You'll have to use SqlFieldsQuery to select specific objects/fields. _key and _val fields represent key and value objects. Also, use fully-qualified table name or an alias before field names. The following SqlFieldsQuery will return Order and Trade objects in a list: "select o._val,

SQL join Query

Hi I have a couple of questions about SQL join queries: I can only use "select *", I get exceptions if I specify tables/alias rather than *, and this "select *" returns the value objects from the first table (or cache) of the join, nothing else. For example, if my query string is

Re: IGFS: Root of secondary backing store

Hi Kobe, "uri" parameter is used by Hadoop infrastructure (in particular, FileSystem.get() method [1]). And as far as I know Hadoop considers only authority [2] part of the URI to extract file system type, credentials and "coordinates" (host, port). Thus, in your example, you should pass

Re: Uberjar for IGFS 1.5.0

Hi Kobe, There is no uberjar for IGFS. If you want to use only IGFS without Hadoop, then just include* ignite-core* [1]. If you want to link IGFS with Hadoop file systems, then you should add *ignite-hadoop* [2] dependency as well. [1]
