I was thinking about that before. Couldn't really decide, and then I took a
look at DeleteHBaseRow and FetchHBaseRow and decided to keep it consistent.
> NIFI-4833 Add ScanHBase processor
> ---------------------------------
>
> Key: NIFI-4833
> URL: https://issues.apache.org/jira/browse/NIFI-4833
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Ed Berezitsky
> Assignee: Ed Berezitsky
> Priority: Major
>
> Add ScanHBase (new) processor to retrieve records from HBase tables.
> Today there are GetHBase and FetchHBaseRow. GetHBase can pull entire table or
> only new rows after processor started; it also must be scheduled and doesn't
> support incoming . FetchHBaseRow can pull rows with known rowkeys only.
> This processor could provide functionality similar to what could be reached
> by using hbase shell, defining following properties:
> -scan based on range of row key IDsÂ
> -scan based on range of time stamps
> -limit number of records pulled
> -use filters
> -reverse rows
