Subject [jira] [Commented] (FLINK-3358) Create constructors for FsStateBackend in RocksDBBackens
Date Mon, 08 Feb 2016 10:47:39 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15136800#comment-15136800

Aljoscha Krettek commented on FLINK-3358:
-----------------------------------------

I think {{MemoryStateBackend}} is useless, except for simple testing. With any marginally
larger state it will immediately fail, IMHO.

So I vote to have a constructor that implicitly creates a FsStateBackend.

> I think no user understands what they are supposed to do when they should define a "backing
state backend".
> The most common thing will probably be that the RocksDB snapshots are backed up to HDFS
and that this is also the backing state backend.
> A simple constructor with a single URI/Path/String that configures both at the same time
should be added, to make this accessible to users.
