Hi Venkat,
Could you setup *constistentId* (IgniteConfiguration#setConsistentId) for
3 server nodes and add these ids to the baseline topology
using ignite.cluster().setBaselineTopology(nodes);
Please setup the baseline and activate the cluster as described in
https://apacheignite.readme.io/docs
Hi
I would like to know the added advantages of using Cluster of Nodes instead
of a single node(single node is sufficient for my data volume) in my use
case . All the operations are sql queries. And if I use a cluster of nodes,
the result set of a query will always be present on a single node(due
I am using Apche Ignite with zookeeper based discovery using curator
framework.
Do I need to open any port on my ignite node like TCP based discovery, in
order for this to work?

You can specify the port your zk is running on as shown in [1], and it should
be opened

Why? Queries and get\put share same resources. So, they will affect each
other.

I've just fixed possible root cause in master [1]. However, as exact use
case details is not known, may be it was something else.
Is it possible to provide more info on the use case: cache configuratioh,
model classes?

Hi!
If you add more nodes to your cluster, you'll get performance boost,
because queries
will be executed in a distributed manner.
But this boost will be noticeable only starting from some particular data
volume, because
distributed query execution is associated with some overhead.
You will also
You should open the port, specified as a *localPort* in *TcpDiscoverySpi *
configuration.
The same for communication SPI and other protocols, that are used in your
cluster, like JDBC, REST, etc.
The only difference in Zookeeper-based discovery is that Zookeeper is used
to find other nodes on the n
Hi,
We have 2 nodes(client&server) and using ignite native persistence.
In cache we have around 3lakh records.
We are querying from Client node and using cursor.getAll() to get the
resultset.
If we execute a query which needs to returns 10k records (ex:select * from

Hi,
Is there any configuration with which we can restrict access to a cache
based on user privileges ?
In a production environment, how does access restriction to different cache
are enforced ?

Hello Manu!
Can you also provide a test that will show that the problem exists, and
that the fix does something helpful? Preferably in the form of code, but
"steps to reproduce" may work too.
Other than that, I recommend you creating a pull request for
https://github.com/apache/ignite/
and a JIRA
Have you tried adding indexes to frequently searched fields ? Indexing can
make searching the cache quite faster

I am updating using remote entry processor, does that also need to copy

Hi team,
I'm getting strange exception when trying to save Key/Value pair.
When I tested locally everything was fine.
Now I deployed application to servers cluster and stuck with this error.
What does it mean? My both Ignite server nodes are UP.
Here is configuration for this cache:
Here is client code which fails:
public void storeRefreshToken(UUID uid, UUID refreshTokenID) {
IgniteCache> cache =
getRefreshTokenCache();
try (Transaction tx = startTransaction()) {
LinkedList ids = cache.get(uid); //getting error

Siva,
The execution plan shows, that no indexes are used. If you create an index
on *EntityType* field, it should make the performance better.
Also if you make all data be stored in memory, then performance of select
queries will be better. Otherwise you will be limited by the performance of
your
Vishwas,
There is no such possibility in Ignite, as far as I know.
You will have to implement a security layer on top of Ignite yourself, if
you want to have such functionality.

Most of my operations are transactions: PESSIMISTIC, SERIALIZABLE that touch

I have been playing with this for a while, and managed to get an external

Some points:1. Used TcpDiscoveryKubernetesIpFinder for sever nodes
2. Exposed pods via NodePort on custom ports (higher than 3); more flexi
Hi Denis,
Thanks for the reply.
Is this not needed. How does the isolation between different applications
happen ?
One thing that comes to my mind is, we can create different data regions and
put the cache needed for specific application in these data regions. Is this
the right approach ?

Hi,
We want to use hive as a 3rd party persistence for ignite. To achieve this
can you let us know how to take it forward. From the documentation, i
understand that we need to implement the CacheStore interface for achieving
this.
How can we make it generic enough irrespective of any schema?
