Subject [jira] [Commented] (HADOOP-15193) add bulk delete call to metastore API & DDB impl
Date Mon, 08 Oct 2018 17:23:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16642189#comment-16642189
] 

Steve Loughran commented on HADOOP-15193:
-----------------------------------------

I'm wrong.

* We already have a bulk directory delete {{deleteSubtree(path)}}; theres no performance gain
in moving to providing a list of operations to the DDB API. 
* yes, you do need all those markers

without any speedups, closing as a WONTFIX

> recursive dir delete (and any future bulk delete API like HADOOP-15191) benefits from
using the DDB bulk table delete call, which takes a list of deletes and executes. Hopefully
this will offer better perf.
