Sergey Shelukhin commented on HIVE-11675:
-----------------------------------------

[~prasanth_j] can you review? The new files are mostly moved/renamed code, with 
some small changes. Every time this patch sits for a while it gets a lot of 
conflicts.

> make use of file footer PPD API in ETL strategy or separate strategy

> Need to take a look at the best flow. It won't be much different if we do 
> filtering metastore call for each partition. So perhaps we'd need the custom 
> sync point/batching after all.
> Or we can make it opportunistic and not fetch any footers unless it can be 
> pushed down to metastore or fetched from local cache, that way the only slow 
> threaded op is directory listings
