This page explains how you can delete streams in Macrometa.
- Web Console
- Python SDK
- JavaScript SDK
- API - Python
- API - JS
- CLI
Delete a stream.
Click Streams.
Macrometa displays a list of streams and their attributes.
Click the trash can icon next to the stream that you want to delete.
Confirm your choice.
Macrometa permanently deletes the stream. You can re-create the stream, but you cannot undo the deletion.
You must Install the Python SDK.
from operator import concat
from c8 import C8Client
# Connect to GDN.
URL = "play.paas.macrometa.io"
GEO_FABRIC = "_system"
API_KEY = "XXXXX" # Change this to your API key
is_local = False
prefix_text = ""
demo_stream = "streamQuickstart"
client = C8Client(protocol='https', host=URL, port=443, apikey=API_KEY, geofabric=GEO_FABRIC)
# Get the right prefix for the stream
if is_local:
prefix_text = "c8locals."
else:
prefix_text = "c8globals."
def deleteStream():
""" This function deletes a stream """
if client.has_stream(demo_stream, local=is_local) is False:
print("Stream does not exists")
else:
client.delete_stream((prefix_text + demo_stream))
print("Stream deleted")
deleteStream()
You must Install the JavaScript SDK before you can run this code.
