Hi, putAll() for atomic cache forces it to lock all keys and make this entry group updated atomically. I think it would be enough to reduce batch size or to use IgniteDataStreamer, if it's an initial data load.
No need to change direct memory size, because Ignite off-heap doesn't rely on it. Thanks! -Dmitry. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
