Re: ClusterTopologyServerNotFoundException

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

Ignite Single Node vs Cluster of Nodes

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

Using Apache Ignite with Zookeeper

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? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Using Apache Ignite with Zookeeper

You can specify the port your zk is running on as shown in [1], and it should be opened https://apacheignite.readme.io/docs/cluster-config#zookeeper-based-discovery Roman On Thursday, April 5, 2018, 4:48:05 p.m. GMT+9, monalsinha wrote: I am using Apche Ignite with zookeeper based d

Re: Upgrade from 2.1.0 to 2.4.0 resulting in error within transaction block

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? [1] https://issues.apache.org/jira/browse/IGNITE-8147 On Mon, Apr 2, 2018 at 1

Re: Ignite Single Node vs Cluster of Nodes

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

Re: Using Apache Ignite with Zookeeper

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

Ignite Sql Query Execution time is too long

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 Entity Where EntityType='Igni

Lucene CorruptIndexException (checksum failed) on GridLuceneIndex - suggested patch

Hi, *GridLuceneOutputStream* has a bug on */copyBytes/* method and *GridLuceneInputStream* on */readBytes/* method for direct calls from GridLuceneOutputStream. On both methods internal GridLuceneOutputStream's CRC is not updated, so we get /org.apache.lucene.index.CorruptIndexException: checksu

Cache access based on the user previleges

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 ? Regards, Vishwas -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Lucene CorruptIndexException (checksum failed) on GridLuceneIndex - suggested patch

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

Thanks Pavel for reply. /"When you store entries into the off-heap, any update operation requires copying value from the off-heap to the heap." / I am updating using remote entry processor, does that also need to copy value to calling heap? If yes then no benefit using entry processor here, I can

Failed to lock keys (all partition nodes left the grid)

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:

Re: Ignite Sql Query Execution time is too long

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

Re: Cache access based on the user previleges

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. Denis чт, 5 апр. 2018 г. в 20:19, vbm : > Hi, > > Is there any configuration with which we can restrict access to a c

I have 2 different caches C1, C2 on 3 nodes N1, N2, N3. I want to configure it in the most possibly reliable way to avoid any inconsistency and data loss, so both caches are REPLICATED, TRANSACTIONAL, FULL_SYNC. Most of my operations are transactions: PESSIMISTIC, SERIALIZABLE that touch both cac

Re: Cache access based on the user previleges

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 ? Rega
