It seems like the main issue is caused by not converting the decoded string to a dictionary before passing it to MySchema
. Since you mentioned that the output is in JSON format, you can use the json.loads()
function to convert the decoded string to a dictionary.
Here's the modified code with the necessary changes:
In this code, I've added the 'String to JSON'
step to convert the decoded string to a dictionary using json.loads()
. This should fix the TypeError you encountered.
Regarding data masking and running SQL within Apache Beam, you can use the beam.Map()
and beam.SqlTransform()
functions. Here's an example of how to mask the user_id
field and run a simple SQL query to filter records with a specific event_id
:
In this example, I've added a mask_user_id
function to mask the user_id
field, a Mask user_id
step to apply the data masking, and a Filter specific event_id
step to filter records using SQL.
