@@LearnGoogleCloudwithMahesh Mahesh, I tried the template method and got it. When I tried with multiple rows on single payload it does not accept. Can you guide how to get that done in python? Checked many links. But they are not giving clear explanation
Can there be two pipelines for a same topic ? 1. from pubsub to bquery 2. from pubsub(the same topic) to another pubsub? in that case will there by any loss of data for any of the flow ?
Thanks Mahesh for the quick tutorial. Two questions in relation to this- 1. Can we stream messages from multiple pub-sub topics and put it into one Big-query table? 2. Can we connect multiple pub-sub topics to be processed one Dataflow Job? Thanks again.
Hi Raghav, both 1 & 2 is possible but not using the template which I showed in the video. You need to built your own dataflow pipeline written in Java. Thanks
It's good video and how can we pass the changed data to pub/sub topic and how to load that to bigquery child table.I will be more thankful if i will get approach.Main goal is we have to pass the changed data from table a to table b with in bigquery.
Good tutorial. How does tmp bucket works? If I have a 2 jobs inserting data to 2 different BQ table, should I give 2 different tmp bucket path or same for both is ok ?
@@LearnGoogleCloudwithMahesh Thanks. Thanks for the reply. Do you know any article/TH-cam video to read more about the tmp folder? I didn't get anything about it online.

Hi bro Bro I have a scenario pls answer if you know this bro it would great help Bro I have 2 files(1 is .csv and 2nd is .json type) in my system I have to move those files to bucket(in bucket I have 3 folders(1st raw_zone, 2nd cleaning zone, 3rd destination folder)) Now bro I have to move those 2 files to bucket what are the ways I came move to bucket (I know to move files to bucket via cloud shell,by normally uploading to bucket) is there is any other method bro 2) I need to Tigger the pipeline(this pipeline should be designed in the way that duplicates,null values must be removed in the files) and for triggering I have used cloud functions(when the file loaded in bucket it should sense and trigger the cleaning pipeline) in cloud function whatt code I should put bro to trigger the pipeline After triggering the file goes to the pipeline and the cleaning(lyk removing duplicates and nulls happens) and move the o/p to cleaning_zone Bro of possible pls help me bro
Hi Mahesh, would you be able to explain the how the data from pubsub extracted and loaded into bigquery using SQL dataflow job without uploading schema into data catalog??.
@@LearnGoogleCloudwithMahesh Hi Mahesh but this template is direct streaming but for Bq writing those records one by one is not advisable right. Can you explain how do we implement the windowed writes here
@@ravitejacoolkuchipudi This is using the built-in template. For windowing via Apache Beam please refer to beam.apache.org/documentation/programming-guide/#windowing

Hi Deepika, UDF in BigQuery is supported by Javascript and not Java. github.com/GoogleCloudPlatform/bigquery-utils/tree/master/udfs/community contains many useful UDF
Short, crisp, to the point and absolutely beautiful, Mahesh. Very useful.
Thanks Ananda
Thanks Mahesh for the quick tutorial!
Thanks Jose
i tried giving a larger amount of data in publish message
will it take more time to reflect in the bq table?
Good content to get started with dataflow and pubusb.

Same tmp bucket can be used. Tmp bucket is used for staging/ interim processing purpose

Hi , how can we connect a DB table to Pub Sub topic to get change data capture
Pub/Sub -> Dataflow -> Cloud SQL is the option.

I have not tried this option
Could you do another like this but using CloudSQL instead using Pub/Sub ?
There a JDBC to BigQuery template available.

Hi Deepika, UDF in BigQuery is supported by Javascript and not Java. github.com/GoogleCloudPlatform/bigquery-utils/tree/master/udfs/community contains many useful UDF
Instead of simple table schema I need to create nested schema as the message is in nested json format
You need to extend the code to achieve this. The template does not support nest json format

Since it is Google Template to transform you have use Javascript or write a Custom Dataflow template in Java or Pythin
