I got this answer from GCP support. Lukasz and Vishwas, any comments. Hello,
the Dataflow specialist has reached me back. I will now expose what they > have told me. The answer to your question is no, Apache Beam does not > support Schema Registry. However, they have told me that you could > implement the calls to Schema Registry by yourself as Beam only consumes > raw messages and it is user's responsibility to do whatever they need with > the data. This is based on our understanding of the case that you want to > publish messages to Kafka, and have DF consume those messages, parsing them > based on the schema from the registry. I hope this information can be > useful to you, let me know if I can be of further help. > Yohei Onishi On Thu, May 9, 2019 at 8:34 PM Yohei Onishi <vivre...@gmail.com> wrote: > Thanks, > > I explicitly set file location and password in JAVA_TOOL_OPTIONS and > Consumer Factory. > Consumer Factory downloads keyStore and trusStore from GCS to local as > follows. > > https://stackoverflow.com/questions/42726011/truststore-and-google-cloud-dataflow?noredirect=1&lq=1 > > Then I got FileNotExecption like below.
