Subject Re: How IGFS keep sync with HDFS?
Date Tue, 29 Nov 2016 11:17:59 GMT
If IGFS can't hold more input data, will it flush data to HDFS? How IGFS
flush data to HDFS? Async or sync?

If it a async mode, when IGFS can't hold more data, it will using cache
expire policy. And if the data which is expired is not persisted to HDFS
timely, the data will be lost.  Is is possible?
