Hi can you please me how to move the tables from Oracle to big query using google dataflow
Hi bro.. good day.. i have one query.. is it possible to delete bigquery records after processed all the records using dataflow job in gcp. Using java api.. please provide a solution if it is possible...
Nice video ..I am able to execute the DataFlow.. Thanks
Good realtime handson experience. I assume when I create Data pipeline using Dataflow which get executed when I click on RUN JOB. How I can use this pipeline for daily data load from GCS to BQ ? is this possible with Dataflow or do I need tool like Cloud Composer to schedule this job at certain intervals ?
Cloud composer is too costly , you can schedule it using cloud scheduler , check this video for your use case

How to load csv file with comma in data? do you know how to escape the comma? thanks
Comma is deliminator or its part of data?
@@techtrapture It's part of the data, like for example the column Address has a value of "Bangkok, Thailand"
i have exaclty the same issue with data rows with comma@@sikondyer2068
Can you send me that CSV.format file and all three files to my mail id..??
Share me your email id
Is there need to configure VPC for streaming between cloud spannerto GCP pubsub? I tried to set up and it failed using: "Failed to start the VM, launcher-202xxxx, used for launching because of status code: INVALID_ARGUMENT, reason: Invalid Error: Message: Invalid value for field 'resource.networkInterfaces[0].network': 'global/networks/default'. The referenced network resource cannot be found. HTTP Code: 400."
It depends on how you are streaming...if you are doing it using dataflow which i seem from error then it's an error for dataflow worker vm. So you are missing details in dataflow configuration.
Hi,
I have been using same approach like you but with different CSV file(UDF is same) but I am getting following error (Loyalty Number is Integer column):
Error message from worker: org.apache.beam.sdk.util.UserCodeException: java.util.concurrent.CompletionException: javax.script.ScriptException: :5:12 Expected ; but found Number
obj.Loyalty Number = values[0];
^ in at line number 5 at column number 12
Can you tell me what the error is actually?
Check if datatype of bigquery column and CSV data is same
Hello I am getting the error below.
org.apache.beam.sdk.util.UserCodeException: java.lang.RuntimeException: Error parsing schema gs://fazendo/mentloja.json
Caused by: java.lang.RuntimeException
Caused by: org.json.JSONException
Can you help me?
One more Question:- Why do we need to specify temp folders here?.
During job execution it stores some metadata and temporary staging files in temp folder. You can monitor it during job execution
How can we load the same data from csv file to pubsub topic and then through dataflow job in bigquey ?
First thing you need to create dataflow job with template "Text files on Cloud storage to Pub/Sub" and now to load data from pub/sub to bigquery you don't need dataflow , Google added new subscription option for pubsub where we can directly load to BQ.
Can you share the CSV file?
Help me with your email id , I will share it with you
Can you also attach the .csv file so that we can download and use?
Sure, Can you share me Email id , i will share it with you for now.
@@techtrapture I've used another .csv file for now... thank you
Also, when trying to give the bigquery dataset name while creating the job i.e project ID:datasetname it is giving error : "Error: value must be of the form ".+:.+\..+"".... how to resolve this? Also, when I am giving the table name, it says' Table not found'
Use format
Projectname.datasetname.tablename
@@techtrapture I am doing the same, still the same error
How to create USD as I do not have any java knowledge
USD?
I think by USD he mean user define function
can you pls share .csv file
Hello I am getting below error.
org.apache.beam.sdk
.util.UserCodeException: java.lang.NoSuchMethodException: No such function transform
at org.apache.beam.sdk.util.UserCodeException.wrap(UserCodeException.java:39)
why so
This is something related to your code you are using...don't think anything related to GCP environment
@@techtrapture Yes you are correct that is with invalid function name inside the code.
Thanx for prompt reply... :)
@@rahulhundare glad you found it.
