SQLQuery and Datatypes

Hi My cached object is Binarylizable. I am using SQLQuery and SQLFieldQuery. In some cases I need to query on a hardcoded/fixed filter e.g. Name = 'xyz'. Same usecase for Long, Date, TimeStamp datatype as well. Basically not using setArgs(). I see it works fine for String, Int, Long. - Can

Master-Worker Pattern Possible In Ignite?

I've used GigaSpaces in the past and I'd like to know if I can use Ignite in a similar fashion. Specifically, I need to implement a master-worker pattern where one set of process writes objects to the in-memory data grid and another set reads those objects, does some processing, and possibly

Re: Pessimistic TXN did not release lock on a key, all subsequent txns failed

Andrey, we never start a txn on the client side. The key that gets locked on our end and stays locked even after a successful txn is never read or updated in a txn from the client side. Are you also able to reproduce the key remaining locked issue? Thanks, Binti -- View this message in

Re: Index

Hi Sam, Default is 'null' obviously, it is by bad design and here is a ticket [1]. It is already fixed in 2.0, where index is SORTED by default. [1] https://issues.apache.org/jira/browse/IGNITE-4511 On Fri, Apr 21, 2017 at 10:00 PM, javastuff@gmail.com < javastuff@gmail.com> wrote: >

Re: Index

Resolved it! I used default constructor for QueryIndex and missed setting IndexType. This resulted into missing index. Added /"idx.setIndexType(QueryIndexType.SORTED)"/, able to see index on H2 debug console. What is the default IndexType? Is it expected to not throw error when IndexType is not

Hi, I try to check your example at near time. But I wan to know hot to do that: 1) I should start empty Ignite server on dedicate machine. 2) After a empty server start, need to begin your example with n more then 1000. Is it correct scenario? -- View this message in context:

Re: What is the difference between starting a node using Java application, and manual starting?

Is that entirely true? Plugins don't start when you simply just start Ignite with Ignite.bat or Ignite.sh unless you package your particular class among the Ignite jars and add an org.apache.ignite.plugin.Pluginprovider file to META-INF/services. Or am I missing something. Best, Rick -- View

Re: Failing DataStreamer beacuse of minor version change

You don't need to handle it, as it mentioned in exception message - "DataStreamer will retry data transfer at stable topology ". It will retry right after topology will be updated. If you don't have any other exceptions - data loading finished successfully 2017-04-21 15:54 GMT+03:00 Alper

Re: IgniteCacheProxy connection failure in REPLICATAED mode

Hi Rick, Looks weird. Cache operation on replicated cache on server node should not failed when other node leaved. Would you please attach logs? Ignite 2.0 ETA should be release on next week. But seems, it may delays for 1-2 weeks as there is neither node freeze happened nor vote started. On

Hi, So how should I handle that exception? Should I just ignore it? Is there a way I can know when the data streamer successfully deliver after getting that error? I just want to know if data loading/rebalancing finished succesfully. On Fri, Apr 21, 2017 at 2:10 PM, Evgenii Zhuravlev

Re: What is the difference between starting a node using Java application, and manual starting?

Hi, If under manually started you mean using ignite.sh(.bat) script, then there actually is no difference, because at the end it calls the same Ignition.start() method (Spring configured app as well). But with programmatic starting you can run more than one node in single JVM. This may be useful
