            Debugging a Google Dataflow Streaming Job that does not work expected
            Asked 2022-Jan-26 at 19:14

            I am following this tutorial on migrating data from an oracle database to a Cloud SQL PostreSQL instance.

            I am using the Google Provided Streaming Template Datastream to PostgreSQL

            At a high level this is what is expected:

            1. Datastream exports in Avro format backfill and changed data into the specified Cloud Bucket location from the source Oracle database
            2. This triggers the Dataflow job to pickup the Avro files from this cloud storage location and insert into PostgreSQL instance.

            When the Avro files are uploaded into the Cloud Storage location, the job is indeed triggered but when I check the target PostgreSQL database the required data has not been populated.

            When I check the job logs and worker logs, there are no error logs. When the job is triggered these are the logs that logged:

            This answer is accurate as of 19th January 2022.

            Upon manual debug of this dataflow, I found that the issue is due to the dataflow job is looking for a schema with the exact same name as the value passed for the parameter databaseName and there was no other input parameter for the job using which we could pass a schema name. Therefore for this job to work, the tables will have to be created/imported into a schema with the same name as the database.

            However, as @Iñigo González said this dataflow is currently in Beta and seems to have some bugs as I ran into another issue as soon as this was resolved which required me having to change the source code of the dataflow template job itself and build a custom docker image for it.

            You need to either configure them as mirrors in your settings.xml or replace them by https repositories (if those exist).

            Assuming that modifiedAt is a property you added, I would expect the JSON in Dataflow to match the Datastore rest api (https://cloud.google.com/datastore/docs/reference/data/rest/v1/Entity). Which would mean you probably want row.properties.modifiedAt . You also probably want to pull out the timestampValue of the property (https://cloud.google.com/datastore/docs/reference/data/rest/v1/projects/runQuery#Value).

            PubSub to BigQuery - Dataflow/Beam template in Python?
            Asked 2021-Feb-21 at 16:20

            Is there any Python template/script (existing or roadmap) for Dataflow/Beam to read from PubSub and write to BigQuery? As per the GCP documentation, there is only a Java template.

            You can find an example here Pub/Sub to BigQuery sample with template:

            An Apache Beam streaming pipeline example.

            It reads JSON encoded messages from Pub/Sub, transforms the message data, and writes the results to BigQuery.

            Here's another example that shows how to handle invalid message from pubsub into a different table in Bigquery :

            ANSWER

            Answered 2021-Jan-24 at 21:53

            This error was being caused because after every 10 seconds the pub/sub resent the messages that had not yet been acknowledged. This caused the total number of messages to grow rapidly as the number of devices sending the messages and the rate at which they sent them was already very high. So I increased this wait time to 30 seconds and the system calmed down. Now there is no large group of unacknowledged messages forming when I run the pipeline.

            Pub/Sub csv data to Dataflow to BigQuery
            Asked 2021-Jan-02 at 22:47

            My pipeline is IoTCore -> Pub/Sub -> Dataflow -> BigQuery. Initially the data I was getting was Json format and the pipeline was working properly. Now I need to shift to csv and the issue is the Google defined dataflow template I was using uses Json input instead of csv. Is there an easy way of transfering csv data from pub/sub to bigquery through dataflow. The template can probably be changed but it is implemented in Java which I have never used so would take a long time to implement. I also considered implementing an entire custom template in python but that would take too long. Here is a link to the template provided by google: https://github.com/GoogleCloudPlatform/DataflowTemplates/blob/master/src/main/java/com/google/cloud/teleport/templates/PubSubToBigQuery.java

            Sample: Currently my pub/sub messages are JSON and these work correctly

            Very easy: Do nothing!! If you have a look to this line you can see that the type of the messages used is the PubSub message JSON, not your content in JSON.

            So, to prevent any issues (to query and to insert), write in another table and it should work nicely!

            The CDC solution you linked to includes the initial copy as part of its normal operation. When you first start it up, it will copy the current contents of the DB first, then continue to copy any updates.
