[jira] [Commented] (SAMZA-537) RocksDB java TTL support

["Yan Fang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SAMZA-537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522828#comment-14522828 ] 

Yan Fang commented on SAMZA-537:
--------------------------------

Added few comments in the RB.

BTW, RB: https://reviews.apache.org/r/33735/

Just one question about this feature: what will happen if we openWithReadOnly the same db that is opened and being written by another application? Will we see all the values, even some of which are not seeable in the open-and-writing application (because TTL)?

> Looks like RocksDB now has support TTL in java as well (only present in C first).

> It would be great if we can add support for this, we would have to do two things:
> 1. Make a new RockDB java release
> 2. expose the configuration in Samza java
