> I was looking through the code in order to understand better how RDD is persisted to Tachyon off-heap filesystem. It looks like that the Tachyon filesystem is hard-coded and there is no way to switch to another in-memory filesystem. I think it would be great if the implementation of the BlockManager and BlockStore would be able to plug in another filesystem.
> For example, Apache Ignite also has an implementation of in-memory filesystem which can store data in on-heap and off-heap formats. It would be great if it could integrate with Spark.
