[jira] [Commented] (KAFKA-9168) Integrate JNI direct buffer support to RocksDBStore

    [ https://issues.apache.org/jira/browse/KAFKA-9168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17058193#comment-17058193 ] 

Sophie Blee-Goldman commented on KAFKA-9168:
--------------------------------------------

Thanks [~sagarrao], marking this as a blocker for 3.0 since we unfortunately need to wait for the next major release before bumping the major version of rocksdb (they made a number of breaking changes that Streams users are unfortunately exposed to).

That said, this patch has the potential for some pretty significant performance improvements in addition to opening the door for other desirable features that aren't available to RocksJava users. Definitely one of the stronger motivations to consider a workaround that allows upgrading without introducing breaking changes to user code...
