I'm trying to read from ksql in python with this script:
from ksql import KSQLAPI
client = KSQLAPI('http://0.0.0.0:8088',)
columns = ['id INT','name VARCHAR']
client.create_stream(table_name='students', columns_type= columns, topic='students')
query = client.query("SELECT name FROM students WHERE id = 1 ")
for student in query:
print(student)
I was expecting a sequence of objects, as the documentation explains, instead it returns me a string representing pieces of an array of objects, with headers and at the end, a "RuntimeError: generator raised StopIteration" (each row is generated separately):
[{"header":{"queryId":"transient_STUDENTS_5788262560238090205","schema":"`NAME` STRING"}},
{"row":{"columns":["Alex"]}},
]
---------------------------------------------------------------------------
StopIteration Traceback (most recent call last)
[...]
The above exception was the direct cause of the following exception:
RuntimeError Traceback (most recent call last)
[...]
RuntimeError: generator raised StopIteration
This way I have to handle the exception or I have to break the loop when I find the ']' character. Also, I need to clean up each string because it is not a valid JSON (due to the final comma and new line), before deserializing it into a Python object with json.loads(str).
