IREADFAST SERIAL

Subscription created in command shell: gcloud pubsub subscriptions create projects//subscriptions/taxi-ride-client -topic=projects/pubsub-public-data/topics/taxirides-realtime -ack-deadline=60 -message-retention-duration=6h.Service account file is created with Project/Owner role and credential file downloaded in JSON format.Still I am curious, how this should be done using python and pure PubSub (without Beam). But it easily processes 9 000 000 messages hourly. That is a different library and different architecture. That suggest that I have problem with the acknowledgement.īy the way I implemented the solution using GC DataFlow with first step as reading from the PubSub topic and that is working fine under Python. I also ran this small program in 5 separate copies to read from the very same subscription, but even in that case I could not make a difference. Anyhow I also tried a totally empty callback that contained only the acknowledgement line.

The stream producing some 8-10 million records per hor out of which less than 0.5% matches the IF condition in my callback. iReadFast uses the RSVP (Rapid Serial Visual Presentation) method to display the document one word at a time (or a few words at a time) at adjustable speed. Subscr_future.result(timeout=600) # running for 10 minutes Download iReadFast for iPhone for iOS to with iReadFast you can read any document much faster. Print('Listening for messages via: '.format(subscription)) Subscr_future = subscriber.subscribe(subscription, callback=callback) Subscription = subscriber.subscription_path(project_name, subscription_name) Subscriber = pubsub_v1.SubscriberClient() Messages are arriving to my program, but either processed slow or improperly.Īm I doing something wrong, or is Python too slow for this? Here is my code: import os

I tried running the same code from my home Windows 10 PC, from a GCP-based Ubuntu VM and from the GCP console terminal with the same result.Īdditional info: In one of my GCP projects I created a subscription 'taxi-ride-client' for the public projects/pubsub-public-data/topics/taxirides-realtime PubSub topic and my application reading that. 'Unacked message count' is constantly increasing whatever I am doing (even if I purge the messages before running my code). I am trying to read messages from the realtime public projects/pubsub-public-data/topics/taxirides-realtime stream, and it seems I am not processing the data fast enough or there is a problem with acknowledgement. iReadfast is a text reading program which lets you read and comprehend text much faster by displaying just one word per time. iReadfast is a speed reading program which permits reading and comprehending any electronic text at a speed much faster than normal.
