[jira] [Commented] (SPARK-20641) Key-value store abstraction and
implementation for storing application data
[ https://issues.apache.org/jira/browse/SPARK-20641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16338402#comment-16338402 ]
Marcelo Vanzin commented on SPARK-20641:
----------------------------------------
[~rxin] sorry I missed you comment. As I explained in the spec, I chose LevelDB because Spark already depends on it. We can definitely add a RocksDB implementation if it's better, and I tried to create the abstraction so that it's not too hard to add these things later on. The HDFS support sounds like an interesting things to have.
