Re: Ignite with Cassandra

The reason is in *"id"* field. According to the persistence descriptor, cache key will be stored in "id" field, but at the same time User POJO class also has such field. There are several options to fix this: 1) Specify another column mapping for Ignite cache key. For example: ** 2) Specify non d

Re: how to automatically exit JVM when the node stops?

Hi, I don't think there is a generic solution for cases when an Ignite node is embedded into other application. You will always need to figure out what to do with other components of this application. You can listen to Ignite events (e.g., EVT_NODE_SEGMENTED) and act accordingly in the listener.

I am trying to do the following: CacheManager cm = Caching.getCachingProvider().getCacheManager(); Cache cache = cm.getCache("my-cache"); At this point, cm points to an instance of org.apache.ignite.cache.CacheManager and cache points to null. I figured that Ignite would simply create the cache

Hi, In FULL_ASYNC mode the API call returns before the update message is sent to a remote node, let alone the response receipt from the remote node. This means that in FULL_ASYNC mode you can stop your client even before the grid knows that you wanted to put something in the cache. You need to use
