Hello, Thanks a lot, Ilya. According to this snippet, It should work when a DefaultDataRegion is configured, as you mention. I have tested and checked that this function returns true but it doesn't work, the AtomicSequence I am expecting to be persistent is not persisted. >From my point of view,

Hi, Topology version is 67. Ignite version is 2.7.6. I went through the thread mentioned by you but in our case, we do not have clients connecting and disconnecting time and again. If a client is connected to the cluster, the topololgy version is increased by 1. The client doesn't disconnect

User-defined event

Hi, I am running Ignite 2.7.0. I am trying to trigger a user-defined event that can be listened by all the nodes in the cluster but in the IgniteEvents API there is just 'recordLocal', which doesn't trigger the listeners in remote nodes. I have looked for a way of doing so in the documentation

Yes, you can create a cache template in two ways: * At startup: add IgniteConfiguration.CacheConfiguration where Name has an asterisk in it, like 'cache-foo-*' * After startup: Ignite.AddCacheConfiguration, same thing with `*` in the Name After that, when you call CreateCache(string name), and
