-----------------------------------
Hi Kenneth!
Sorry I am actually no longer working on Bigtable related stuffs :)
> Read Bigtable Rows by Prefix
> ----------------------------
>
> Key: BEAM-10279
> URL: https://issues.apache.org/jira/browse/BEAM-10279
> Project: Beam
> Issue Type: Wish
> Components: io-java-gcp
> Reporter: Rafi Kamal
> Priority: P3
> Labels: Bigtable
>
> BigtableIO.Read provides a withKeyRange method to specify Bigtable keys
> within a [start, end) range. Unfortunately, it doesn't seem to provide a way
> of reading rows by a common prefix, although Bigtable natively supports this
> feature: [https://cloud.google.com/bigtable/docs/cbt-reference#read_rows.]
> Our use case, we have several "types" in our table, and each type is prefixed
> with the name of the type. The only other way to reading all rows with a
> specific prefix seems to use a RowFilter with row_key_regex_filter set, but
> it looks like that will result in a full table scan.
