Hi Tracy, Here are my answers:
1. Correct. IgniteContext is actually a wrapper around SparkContext which is used to provide connectivity with the Ignite cluster. 2. Please refer to [1] for information about how to load the data into the cache. You can implement your own CacheStore or use IgniteDataStreamer. In any case, you should create an entry per row, having DataFrame as a value doesn't make sense. 3. I think the answer is no. the only thing you need to create the IgniteContext is SparkContext.
