> Key: BEAM-12904
> URL: https://issues.apache.org/jira/browse/BEAM-12904
> Project: Beam
> Issue Type: Improvement
> Components: io-py-gcp, runner-dataflow
> Affects Versions: 2.28.0, 2.32.0
> Environment: Default Python SDK image for environment is
> apache/beam_python3.7_sdk:2.32.0
> Using provided Python SDK container image:
> gcr.io/cloud-dataflow/v1beta3/python37:2.32.0
> Reporter: Krzysztof Korzeniewski
> Priority: P3
> Labels: GCP
> Time Spent: 3h 10m
> Remaining Estimate: 0h

> There are 2 things:
> 1. apache_beam.io.gcp.bigtableio.WriteToBigTable has no support for custom
> App profiles at all
> 2. i've added support to custom DoFn, its passed correctly and works on
> DirectRunner, and even shows correct passed params in Dataflow logs, but
> still uses 'default' app_profile_id.
> Its easy to trigger just by passing not-existent app_profile_id:
> DirectRunner crashes with error, DataflowRunner uses 'default' and crashes if
> 'default' is multi-cluster routing and/or transactional writes are disabled.
> BigTable needs to use single-cluster routing to support transactional writes
> (read-modify-write, check-and-mutate). Thats why i need to use in 1 case
> custom app_profile_id.
> Custom write func:
> {code:java}
> from datetime import datetime, timezone
> import logging
> import apache_beam as beam
> from apache_beam.metrics import Metrics
> from apache_beam.transforms.display import DisplayDataItem
> from google.cloud.bigtable import Client, row_filters
