Subject Re: Ignite Data Grid with write through mode to HDFS with layer of IGFS

Vij,

No, it doesn't. IGFS serves the very different purpose - it is
Hadoop-compatible file system. It means that, for example, you can load
data to IGFS and then query it using Hive. But native Ignite SQL is not
applicable here.
