Fwd: ignite cache get performance issue when Key, Value not exist

Igniters, This is not the first time I hear about from the community side about the performance issue Kevin is talking below. In short if a key is not located in a cache then we will go to an underlying storage. This process will be repeated all the time for the same key and this leads to perf

Re: Persistent storage with Ignite C++

Hi Denis/Igor, I can confirm that I've managed to get this working :) I've got a C++ program running just fine. It uses Ignite C++ with a CacheStoreAdapter-derived Java class that implements persistent storage (MongoDB in this case, but easily replaceable). Thanks for your help, Graham On 6

I have a related question which I have been trying to find the answer to in the docs: Given a cache REPLICATED cache with CacheRebalanceMode.SYNC, is there any meaningful use case for a readthrough handler ? (Is there any situation where the readthrough database can actually produce a result that i

Hi Agneeswaran, You should install Apache Ignite ODBC driver using provided ignite-odbc-install.ini file as described at [1]. After that you are going to be able to connect to the driver using "{Apache Ignite}" as a value for the "DRIVER" attribute. Or simply speaking, you should modify your conne

Hello Kamal, I will repeat, but you can use the ScanQuery. org.apache.ignite.cache.query.ScanQuery#setPartition You have only to find a local partition: Affinity affinity = ignite.affinity(cacheName); List partitions = new ArrayList<>(affinity.partitions()); for (int i = 0; i < affinity.part
