Re: failureDetectionTimeout tuning

[bintisepaha]

We will try this and get back to you. Does it mean that usually the  node
recovers from it, if it were due to GC? Would we also have to remove
joinTimeout?

Re: IgniteCompute.broadcast() stuck

[bintisepaha]

Val, this dump was from the client node which I sent on the original email. 
the zipped up dumps were from all the server nodes that participate in the
distributed cache.

anyways, changing it to run() fixed the issue. But we never understand the
root cause of the hanging, its always that the alternative suggestion works.
And we move on to it without understanding why what we tried first did not
work.

Thanks,
Binti

IgniteCluster API provides startNodes() method that allows to do this

Can you please give me full examples? or a link for this? thanks again

Re: Reassign partitions

[wetnose]

Hi,

We have no global DB behind the grid. We marked our Store with
@CacheLocalStore annotation. But Ignite does not move stored entries when
rebalancig partitions. So we should have more control of partition
assignment to be able to change the assignment manually after storage
synchronization.

Hi,

Your Maven tries to access a repo which is not provided by Ignite build. I

Re: Overall desgn question

[vkulichenko]

Hi Scott,

How many caches are you going to have? Basically, the recommended way is to
have a cache per data type - this makes life easier in most cases. But keep
in mind that each cache will require around 20MB of *heap* memory per node
for its internals. So hundreds of caches can introduce high memory
consumption and you may consider merging some caches in this case.

Re: Server and Client mode per cache

Hi,

You can use CacheConfiguration.setNodeFilter(..) property to specify where
the particular cache will be deployed. If not set, it will be deployed on
all server nodes.

You can try using Ignite C++ client. If you describe your use-case some

What for are you using Ignite for and why do you need to make JNI calls?

Access cache entries in C++ via JNI call

[Caio Nishibe]

Hi, I'm trying to implement a biometric identification system using Ignite.
The first version was not good enough because in my job, for each cache
entry, I was calling a C++ method through JNI to process that entry and the
time to transfer all the data from Java to C++ was killing the performance
of the threads. I've tried to create a C++ Client inside my Java job to run
a ScanQuery, but did not work and I discovered that I cannot create another
JVM instance inside a JNI call.  Is it possible to access all the cache
entries in C++ inside a JNI call?

Reassign partitions

[wetnose]

The AffinityFunction.assignPartitions method is called when a server node
joins or left the topology. Is there a way to reassign partitions for a
cache without changing the topology (e.g. to move a backup partition from
one node to another)?

Server and Client mode per cache

[Yitzhak Molko]

Hi, I am trying to configure ignite that cache A data will be on all nodes
and cache B data on some subset of nodes. In other words for cache A ignite
will be in server mode for all nodes and for cache B ignite will in server
mode for some nodes and in client mode for others.
I think it could be done implementing AffinityFunction API, but I am not
sure is this is a right way to do this.
Is there better way to solve this issue?

Thanks.

We will be employing a data grid off heap, replication implementation. We 
are estimating with the 30% index cache alllowance that we will need 7 gig 
of ram per ignite server node there will be two. We have two  options. 
Create many smaller caches or put everything in a collection using one 
cache.

Are there any recommendations that someone might have as to the best 
approach?

If you specify type on IndexTypes property[1] SQL will be work, but without

The resume field do not be visible from SQL.

Combine SQL and Text Query

[WhiteAncient]

If I have the classic POJO

class Person{
@QuerySqlField
private String genotype;

@QueryTextField
private String resume;
}

How do I query "where genotype = 'male' and resume like '%Hello%'" so that
it hits the lucene index?

Hello,


Please properly subscribe to the mailing list so that the community can

The reason of segmentation in most cases is a delays: like network problem,

Please, check the instructions and try to avoid this issues.

If you have checked already, provide whole logs from all cluster nodes.
