[jira] [Commented] (HIVE-5687) Streaming support in Hive
[ https://issues.apache.org/jira/browse/HIVE-5687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13960948#comment-13960948 ]
Alan Gates commented on HIVE-5687:
----------------------------------
After discussing this with [~ashutoshc] I think this should move from hive/streaming to hive/hcatalog/streaming. This is a non-SQL interface for Hive, and that is the area HCatalog covers. This should be a simple refactor and shouldn't require a re-review.

> Implement support for Streaming data into HIVE.
> - Provide a client streaming API
> - Transaction support: Clients should be able to periodically commit a batch of records atomically
> - Immediate visibility: Records should be immediately visible to queries on commit
> - Should not overload HDFS with too many small files
> Use Cases:
> - Streaming logs into HIVE via Flume
> - Streaming results of computations from Storm
