Hi, I have been working lately quite a lot with Dataflow and Bigtable, using Beam's BigtableIO.
The documentation ( https://beam.apache.org/releases/javadoc/2.17.0/org/apache/beam/sdk/io/gcp/bigtable/BigtableIO.html) shows that BigtableIO is annotated as experimental. The same docs also says that: *this connector for Cloud Bigtable is considered experimental and may break or receive backwards-incompatible changes in future versions of the Apache Beam SDK. Cloud Bigtable is in Beta, and thus it may introduce breaking changes in future revisions of its service or APIs.* However, Bigtable went out of beta in 2016 ( https://cloud.google.com/bigtable/docs/release-notes#June_29_2016) and many of the client libraries (all?) are in GA too (Java went out of beta on September -> https://cloud.google.com/bigtable/docs/release-notes#September_25_2019). So I am wondering if BigtableIO is truly experimental, and whether I should submit a pull request updating the comment about Cloud Bigtable being in beta. Kind regards, Israel
