Physical colocation of Ignite nodes in different JVM's

2018-07-10 Thread Grégory Jevardat de Fombelle
Hello On one hand I have a cluster of Ignite Server nodes target to store a partitioned cache. On the other hand I have some "legacy" compute code running in its own JVM on the same nodes as Ignite nodes. I would like to integrate in this compute JVM's an Ignite client joining the cluster

NearCache

2019-01-16 Thread Grégory Jevardat de Fombelle
Hello Is there any option to have a nearCache in Ignite that store unMarschalled values instead of serialized ones. I ask this for performance reasons. I noticed that for big cached objects, default Java unserialization is quite expensive, like ~ 2 secs for a complex > 100MB object. So in the

java.lang.OutOfMemoryError: Java heap space on server node during cache querying on same node by multiple clients nodes

2019-01-11 Thread Grégory Jevardat de Fombelle
Hello We are facing this exception when multiple clients are trying to read a big cached object using the standard value = cache.get(key). The cached object is a big serialized object that can reach hundreds of MB in size. The server node has 16GB of heap which should be fairly enough for
