[jira] [Commented] (CARBONDATA-1572) Support Streaming Ingest

    [ https://issues.apache.org/jira/browse/CARBONDATA-1572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16205057#comment-16205057 ]

----------------------------------------

[~QiangCai]
I have two questions about the design:

1.Handoff process will convert rows in Streaming-Segment into Batch-Segment ,does it means the records will be deleted from the Streaming-segment and inserted into the batch-segment? So what will happen when a long query is running and the handoff process is done, i.e., Query deleted records from streaming segment and ignore inserted records from batch segment.

2. Will we implement the streaming-segment like HBase, or just put the segment on HDFS? I perfer the first.
