Hi,
You may use it in cases when you use temporary files that should be removed
after node stop, or any other data that don't require persistence.

Hi Dmitriy,
Thanks for explaining. I understand.
In situations using Name node, it's better to use DUAL_SYNC mode.
May I ask one more?

Hi Massayuki,
Ignite itself does not have a concept of a NameNode. It goes directly to
the cluster node responsible for storing the data based on a key's hashcode.
The only time when a NameNode would come into a play, is when Hadoop HDFS
is configured as an underlying write-through file system. B
Hi,
I am trying to use IGFS on HDFS.
If I set DUAL_ASYNC to IGFS mode and execute 'hdfs dfs -put ...', when
does the file info write to HDFS NameNode?
Also, if I set PRIMARY to IGFS mode and put a new file, does the file
info write to HDFS NameNode?
thanks.
