Optimistic Serializable SQL Transactions

Hi Viktor, Could you please clarify a bit, do you need just to load data once/periodically or do you want Ignite to write-back to S3 on updates? If the loading is all you need then create a custom Java app/class that pulls data from S3 and streams into Ignite IgniteDataStreamer (fastest loading te

You can deploy services to client nodes, for example: val service = ignite.services(ignite.cluster().forClients()) service.deployClusterSingleton("TestService", new TestServiceImpl()) If you want to have independent clients, as you currently have, I suspect you’d have to implement your own fail ov

Re: Authenticating communication between nodes using Ignite.Net

Hello! It's hard to say why this may be. Maybe your client can't find one of key files by specified path? If you have a reproducer project which you can share, I could look into it. I can ever take my own keys from Ignite tests, so you don't have to share these. Regards, -- Ilya Kasnacheev ср
