hazelcast

问题 I'm trying to use hazelcast ScheduledExecutorService to execute some periodic tasks. I'm using hazelcast 3.8.1. I start one node and then the other, and the tasks are distributed between both nodes and properly executed. If I shutdown the first node, then the second one will start to execute the periodic tasks that were previously on the first node. The problem is that, if I stop the second node instead of the first, then its tasks are not rescheduled to the first one. This happens even if I

问题 I'm using hazelcast IMap to store my application data. I'm facing small issue. Problem explanation:- When I start the spring-boot application I'm loading database table data into hazelcast. example:- HazelcastInstance hazelCast = Hazelcast.getOrCreateHazelcastInstance(HazelcastConfig.getConfig()); IMap<Integer, String> mapInstance= hazelCast.getMap("data"); mapInstance.put(1,"value1"); mapInstance.put(2,"value2"); mapInstance.put(3,"value3"); mapInstance.put(4,"value4"); But when I fetch same

问题 I am having Jet 0.6 as a backup and some Node.JS process with hazelcast-nodejs-client 0.8.0 installed. I am trying to push to map an object from Node process that is exactly a reflection of similar one on the Jet side. However I don't understand how to make sure on Jet's side this JS object will be serialized/deserialized respectively. I have a feeling I need to indicate to Jet that this JSON object is meant to be Data POJO and proper serialization/deserialization should be used. On the node

问题 I am using istio 1.0.2 version with istio-demo-auth .yaml, and I used hazelcast-kubernetes in the k8s cluster environment. I was using hazelcast-kubernetes in the k8s cluster before, when scale two hazelcast-kubernetes StatefulSet, they can join together, and working with my services. Not using istio that time. Recently our services injected with istio. I try to inject the hazelcast-kubernetes with istio, it was running, but those two hazelcast-kubernetes cannot join together. Do you know how

问题 My use case is as follow: We have about 500 servers running in an autoscaling EC2 cluster that need to access the same configuration data (layed out in a key/value fashion) several million times per second. The configuration data isn't very large (1 or 2 GBs) and doesn't change much (a few dozen updates/deletes/inserts per minute during peak time). Latency is critical for us, so the data needs to be replicated and kept in memory on every single instance running our application. Eventual

问题 I am working with Spring 4 and Hazelcast 3.2. I am trying to add a new record to existing cache with below code. somehow cache is not getting updated and at the same time I don't see any errors also. below is the code snippet for reference. Note:- Cacheable is working fine, only cacheput is not working. Please throw light on this @SuppressWarnings("unchecked")`enter code here` @Transactional(readOnly = true, propagation = Propagation.REQUIRED) @Cacheable(value="user-role-data") public List
