Re: Fetching large number of records

Hi Val, I think No. Correct me if i am wrong. i was looking at following code pieces - 1. JdbcResultSet#next() try { JdbcQueryTask.QueryResult res = loc ? qryTask.call() : ignite.compute(ignite.cluster().forNodeId(nodeId)).call(qryTask);

Re: In-Memory SQL Grid

Igniters, I’ve finished reworking, enhancing and expanding our SQL Grid documentation preparing it to 1.8 release. If you recall, before it was a single page documentation and now it’s a big section that contains, I hope, all the valuable knowledge we can share with Ignite users. Just open

Re: Ignite Cassandra AWS test framework

Hi Val, No, that's not the issue. I would like to follow the AWS ignite-cassandra framework guide on the documentation, but some files the documentation says I should modify are not in the test-package after I build ignite from source. Just to be clear, this is the link to the guide I am

Re: Issue with SQL Query Performance - Post Rebalance Operation

Ganesh, I'm not I understand what you mean here. There is no such a delay, indexes on new node are created right away and updated during the rebalancing. There is no way indexes are temporarily not used due to topology change. If there is a slowdown, most likely it's caused by the rebalancing

Anil, This means that you stopped the embedded client node before it loaded all the data into the cache. Ignite and IgniteDataStreamer provided via setIgnite() and setStreamer methods should not be closed before the Kafka streamer is closed. See the example here:

BinaryObjectImpl is a binary object, while deserialized objects will be shown as your classes. Deserialized objects are not stored by default. However, if you have queries enabled, and do a read on server side (i.e. send a closure there to do a local get), then the deserialized object will be

Re: Failed to process message: Creating partition which does not belong to local node

Hi Yuci, Basically, this error means that affinity function on node A gave node B as a primary node for a key. Node A than sent a request to node B, but affinity on node B doesn't think that this key belong locally. In other words, affinity function worked inconsistently on different nodes.

Hi Yuci, 1.8 in in final testing/bug fixing stage, so it should become available soon. However, "Failed to wait for initial partition map exchange" is a very generic error and can be caused by different circumstances. I would recommend to build from 1.8 branch and run your tests on it ti check if

Re: Package jar file path for sql Query Entity

Re: Package jar file path for sql Query Entity

Hi, I think in your case (when you configured "QueryEntity"), have not necessary to copy classe (schema.jar) to a server. Ignite will by use binary[1] format, and execute SQL (or other query) without deserialization. But I definitly do not understand why it does not work... You can to clarify
