plugin
URL: https://github.com/apache/drill/pull/1272#issuecomment-395294020
@akumarb2010 - I checked in a commit to fix an issue where condition on
non-existing partitions could result in a scan batch with no readers. In such a
scenario I add `partition 0` to scan spec and point `startOffset` and
`endOffset` to end of partition so no messages are actually read. I have also
added test cases similar to the ones discussed earlier in the thread.

> As part of Kafka storage plugin review, below is the suggestion from Paul.
> {noformat}
> Does it make sense to provide a way to select a range of messages: a starting
> point or a count? Perhaps I want to run my query every five minutes, scanning
> only those messages since the previous scan. Or, I want to limit my take to,
> say, the next 1000 messages. Could we use a pseudo-column such as
> "kafkaMsgOffset" for that purpose? Maybe
> SELECT * FROM <some topic> WHERE kafkaMsgOffset > 12345
