Vincent, What type of IgniteDataStreamer you are using? allowOverwrite == true/false? Are you loading data to SQL table or just a regular cache? Are there any indexes exists?
Yes, disabling WAL means you have a risk of losing data while it still remains disabled. Then the initial loading completes you have to re-enable WAL logging. Disabling WAL can significantly increase the loading speed.
