[BEAM-639] BigtableIO: add support for users to scan table subranges
> BigtableIO.Read: expose withStartKey/withEndKey
> ---
>
> Key: BEAM-639
> URL: https://issues.apache.org/jira/browse/BEAM-639
> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-gcp
>Reporter: Daniel Halperin
>Assignee: Daniel Halperin
>Priority: Minor
>
> BigtableIO.Read takes a table and a filter, but does not let the user
> customize the row range. If a user wants to scan a relatively narrow range,
> they can do it by specifying a filter ("starts with abcd") or ("less than
> abcd"), but under the hood Cloud Bigtable will implement this as a full table
> scan -> filter instead of a narrower scan.
> We should expose these setters publicly so that users can implement row scans
> directly.
