Can this be used with local installation of influx db

[arunjose696]

Can FlightSQLClient be used with local installation of influx-db ,

query_client = FlightSQLClient(
    host = "localhost",
    token = token,
   port=8086,
    metadata={"bucket-name": bucket_name})
query = """SELECT *
        FROM table
        """
info = query_client.execute(query)

I got this error when trying to do this

File "<stdin>", line 1, in <module>
  File "C:\Users\arunj\anaconda3\envs\newenv\lib\site-packages\flightsql\client.py", line 123, in execute

I'm also just trying to run this with a local IOx installation. It looks like the SSL verification can be turned off using the insecure parameter:

from flightsql import connect, FlightSQLClient

client = FlightSQLClient(host='localhost', port=8083, insecure=True)
conn = connect(client)
cursor = conn.cursor()
cursor.execute('select * from runs limit 10')
print("columns:", cursor.description)
print("rows:", [r for r in cursor])

I'm now getting a new error:

cursor.execute('select * from runs limit 10')

That's probably related to IOx not yet implementing a few Flight operations.

I got this error . When using insecure parameter in my windows machine.

pyarrow._flight.FlightUnavailableError: Flight returned unavailable error, with message: failed to connect to all addresses; last error: UNKNOWN: ipv4:127.0.0.1:8086: Trying to connect an http1.x server

It looks like you're trying to connect to a InfluxDB 1.x or 2.x. I think Flight only works with IOx which would have port 8083 for the gRPC calls.
