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

[vijayendra bhati]

Hi,
Can some body please provide me any pointers regarding how I can use Ignite 
Data Grid/ In Memory caching with write through/write behind mode and writing 
to HDFS ?
I know Ignite provides IGFS but its different from what I am looking for.
The other way could be I can use IGFS as my In Memory store but is it the right 
approach ?
