            My basic requirement was to create a pipeline to read from BigQuery Table and then convert it into JSON and pass it onto a PubSub topic.

            Because your pipeline does not have any unbounded PCollections, it will be automatically run in batch mode. You can force a pipeline to run in streaming mode with the --streaming command line flag.

            Pub Sub Lite topics with Peak Capacity Throughput option
            Asked 2022-Feb-20 at 21:46

            We are using Pub Sub lite instances along with reservations, we want to deploy it via Terraform, on UI while creating a Pub Sub Lite we get an option to specify Peak Publish Throughput (MiB/s) and Peak Subscribe Throughput (MiB/s) which is not available in the resource "google_pubsub_lite_topic" as per this doc https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/pubsub_lite_topic.

            ...

            ANSWER

            Answered 2022-Feb-20 at 21:46

            If you check the bottom of your Google Cloud console screenshot, you can see it suggests to have 4 partitions with 4MiB/s publish and subscribe throughput.

            Therefore your Terraform partition_config should match this. Count should be 4 for the 4 partitions, with capacity of 4MiB/s publish and 4MiB/s subscribe for each partition.

            The "peak throughput" in web UI is just for convenience to help you choose some numbers here. The actual underlying PubSub Lite API doesn't actually have this field, which is why there is no Terraform setting either. You will notice the sample docs require a per-partiton setting just like Terraform.

            eg. https://cloud.google.com/pubsub/lite/docs/samples/pubsublite-create-topic

            I think the only other alternative would be to create a reservation attached to your topic with enough throughput units for desired capacity. And then completely omit capacity block in Terraform and let the reservation decide.

            MSK vs SQS + SNS
            Asked 2022-Feb-09 at 17:58

            I am deciding if I should use MSK (managed kafka from AWS) or a combination of SQS + SNS to achieve a pub sub model?

            Background

            Currently, we have a micro service architecture but we don't use any messaging service and only use REST apis (dont ask why - related to some 3rd party vendors who designed the architecture). Now, I want to revamp it and start using messaging for communication between micro-services.

            Initially, the plan is to start publishing entity events for any other micro service to consume - these events will also be stored in data lake in S3 which will also serve as a base for starting data team.

            Later, I want to move certain features from REST to async communication.

            Anyway, the main question I have is - should I decide to go with MSK or should I use SQS + SNS for the same? ( I already understand the basic concepts but wanted to understand from fellow community if there are some other pros and cons)?

            Thanks in advance

            Answered 2022-Feb-09 at 17:58

            MSK VS SQS+SNS is not really 1:1 comparison. The choice depends on various use cases. Please find out some of specific difference between two

            1. Scalability -> MSK has better scalability option because of inherent design of partitions that allow parallelism and ordering of message. SNS has limitation of 300 publish/Second, to achieve same performance as MSK, there need to have higher number of SNS topic for same purpose.

            Example : Topic: Order Service in MSK -> one topic+ 10 Partitions SNS -> 10 topics

            if client/message producer use 10 SNS topic for same purpose, then client needs to have information of all 10 SNS topic and distribution of message. In MSK, it's pretty straightforward, key needs to send in message and kafka will allocate the partition based on Key value.

            1. Administration/Operation -> SNS+SQS setup is much simpler compare to MSK. Operational challenge is much more with MSK( even this is managed service). MSK needs more in depth skills to use optimally.

            2. SNS +SQS VS SQS -> I believe you have multiple subscription(fanout) for same message thats why you have refer SNS +SQS. If you have One Subscription for one message, then only SQS is also sufficient.

            3. Replay of message -> MSK can be use for replaying the already processed message. It will be tricky for SQS, though can be achieve by having duplicate queue so that can be use for replay.

            Dataflow resource usage
            Asked 2022-Feb-03 at 21:43

            After following the dataflow tutorial, I used the pub/sub topic to big query template to parse a JSON record into a table. The Job has been streaming for 21 days. During that time I have ingested about 5000 JSON records, containing 4 fields (around 250 bytes).

            After the bill came this month I started to look into resource usage. I have used 2,017.52 vCPU hr, memory 7,565.825 GB hr, Total HDD 620,407.918 GB hr.

            This seems absurdly high for the tiny amount of data I have been ingesting. Is there a minimum amount of data I should have before using dataflow? It seems over powered for small cases. Is there another preferred method for ingesting data from a pub sub topic? Is there a different configuration when setting up a Dataflow Job that uses less resources?

            ...

            ANSWER

            Answered 2022-Feb-03 at 21:43

            It seems that the numbers you mentioned, correspond to not customizing the job resources. By default streaming jobs use a n1-standar-4 machine:

            3 Streaming worker defaults: 4 vCPU, 15 GB memory, 400 GB Persistent Disk.
            4 vCPU x 24 hrs x 21 days = 2,016
            15 GB x 24 hrs x 21 days = 7,560

            If you really need streaming in Dataflow, you will need to pay for resources allocated even if there is nothing to process.

            Options:

            Optimizing Dataflow

            • Considering that the number and size of the JSON string you need to process are really small, you can reduce the cost to aprox 1/4 of current charge. You just need to set the job to use a n1-standard-1 machine, which has 1vCPU and 3.75GB memory. Just be careful with max nodes, unless you are planning increase the load, one node may be enough.

            Your own way

            • If you don't really need streaming (not likely), you can just create a function that pulls using Synchronous Pull, and add the part that writes to BigQuery. You can schedule according to your needs.

            Cloud functions (my recommendation)

            "Cloud Functions provides a perpetual free tier for compute-time resources, which includes an allocation of both GB-seconds and GHz-seconds. In addition to the 2 million invocations, the free tier provides 400,000 GB-seconds, 200,000 GHz-seconds of compute time and 5GB of Internet egress traffic per month."[1]

            You cannot have a single registration to track course work changes for multiple courses, as you can see here:

            Types of feeds

            The Classroom API currently offers three types of feed:

            • Each domain has a roster changes for domain feed, which exposes notifications when students and teachers join and leave courses in that domain.
            • Each course has a roster changes for course feed, which exposes notifications when students and teachers join and leave courses in that course.
            • Each course has a course work changes for course feed, which exposes notifications when any course work or student submission objects are created or modified in that course.

            You have a Flow> here, which means every element of this flow is itself a list.

            The take operator is applied on the flow, so you will take the 3 first lists of the flow. Each individual list is not limited, unless you use take on the list itself.

            So the name transformedListOf3Elements is incorrect, because the list is of an unknown number of elements, unless you filter it somehow in the map.

            To feed a Source, you don't necessarily need to use a custom graph stage. Source.queue will materialize as a buffered queue to which you can add elements which will then propagate through the stream.

            There are a couple of tricky things to be aware of. The first is that there's some subtlety around materializing the Source.queue so you can set up the subscription. Something like this:
