GCP - Message from PubSub to BigQuery

I need to get the data from my pubsub message and insert into bigquery.

ANSWER

Answered 2021-Jan-08 at 21:46

In fact, there is 2 solutions to consume the messages: either a message per message, or in bulk.

Firstly, before going in detail, and because you will perform BigQuery calls (or Facebook API calls), you will spend a lot of the processing time to wait the API response.

Message per Message If you have an acceptable volume of message, you can perform a message per message processing. You have 2 solutions here:

You can handle each message with Cloud Functions. Set the minimal amount of memory to the functions (128Mb) to limit the CPU cost and thus the global cost. Indeed, because you will wait a lot, don't spend expensive CPU cost to do nothing! Ok, you will process slowly the data when they will be there but, it's a tradeoff.

Create Cloud Function on the topic, or a Push Subscription to call a HTTP triggered Cloud Functions

You can also handle request concurrently with Cloud Run. Cloud Run can handle up to 250 requests concurrently (in preview), and because you will wait a lot, it's perfectly suitable. If you need more CPU and memory, you can increase these value to 4CPU and 8Gb of memory. It's my preferred solution.

Bulk processing is possible if you are able to easily manage multi-cpu multi-(light)thread development. It's easy in Go. Concurrency in Node is also easy (await/async) but I don't know if it's multi-cpu capable or only single-cpu. Anyway, the principle is the following

Create a pull subscription on PubSub topic
Create a Cloud Run (better for multi-cpu, but also work with App Engine or Cloud Functions) that will listen the pull subscription for a while (let's say 10 minutes)
For each message pulled, an async process is performed: get the data/attribute, make the call to BigQuery, ack the message
After the timeout of the pull connexion, close the message listening, finish the current message processing and exit gracefully (return 200 HTTP code)
Create a Cloud Scheduler that call every 10 minutes the Cloud Run service. Set the timeout to 15 minutes and discard retries.
Deploy the Cloud Run service with a timeout of 15 minutes.

This solution offers a better message throughput processing (you can process more than 250 message per Cloud Run service), but don't have a real advantage because you are limited by the API call latency.

QUESTION

Item.Read does not work according to any of the provided docs

Asked 2020-Nov-04 at 06:36

I have gone through all the types of documentation provided about the CosmosDB Read Item method. But it doesn't seem to work.

ANSWER

Answered 2020-Nov-04 at 06:36

It seems that you pass the wrong key to item("id","key"). When you pass undifined as key of this method, it means you don't define partition key value of document which id is '1' like this screenshot.

I guess your document which id is '1' has partition key value, so cosmos DB can't find the document which id is '1' and doesn't have partition key value. If so, you need to pass your partition key value to item("id","key").

For example, I have a document like below, my code should be like this:

Long story short the error was a syntax/naming error: Re naming the passed variables when i create the new CosmosClient will solve the issue. From my opinion its pretty much dumb that SDK dont throw meaningfull error. Also there are other issues with the SDK i ran into, which connects to partitionKeyDefinition issues. But this thread is considered as solved from my side.

Answered 2020-Jul-05 at 15:33

The issue comes down to this error No Solution Stack named '64bit Amazon Linux 2018.03 v4.7.1 running Node.js' found..

The available options are:

64bit Amazon Linux 2 v5.1.0 running Node.js 12
64bit Amazon Linux 2 v5.1.0 running Node.js 10
64bit Amazon Linux 2018.03 v4.15.0 running Node.js

Once you've chosen the appropriate one for your application enter its value for the SolutionStackName property of the SampleConfigurationTemplate resource.

I have updated this to 64bit Amazon Linux 2018.03 v4.15.0 running Node.js (which appears the closest to what you're trying to deploy) and can confirm it works with the below template

Uploading image files to AmazonS3 using ReactJs

Asked 2020-Feb-13 at 14:15

I am fairly new to web development (currently enrolled in a bootcamp) and have struggled finding the needed resources to incorporate uploading to Amazon S3 in my project. I apologize for the vagueness ahead of time.

I currently have a react app that is pulling images from my AmazonS3 account but I am intending to give the user the ability to upload to my bucket and use/view the images on my website.

I have tried watching tutorials and looking at various GitHub Repo's to identify what I am missing but have been unable to locate a tutorial that involves React, JSX and Javascript. (I've seen jquery, PHP, etc). Ultimately, I know this task is difficult and I am willing to put in the work but felt the need to ask if anyone knows of a useful resource that can help me?

I've tried using the 'aws-nodejs-sample' repo, 'themetoerchef/uploading-with-react' repo, watched a youTube tutorial, I've looked into FineUploader and have read the react-S3-uploader npm files but am unable to connect the dots. Additionally, I've included my AWS access keys in my .env file and tried making query strings to access the S3 bucket.

Is there a better way to go about this or are there other ways to upload with react that may be useful outside of S3?

...

ANSWER

Answered 2018-Jan-17 at 17:17

To upload to s3 from the browser you need to get a signedUrl from an aws sdk which is how aws verifies your identity. In my last application I used skd for nodejs to generate the signedUrl and pass it to my front end application to use in pushing files to s3. You don't have to go that route there is an sdk that can be used by javascript within the browser.

QUESTION

Obtaining room/area information from Forge api

Asked 2018-Oct-15 at 11:10

I need to get room/area objects with the hierarchy of linked objects from the Revit model via Forge. Right now I am using this project as a starting point. Unfortunately, the room information is lost. As far as I understand, it is removed during the translation process. There are some workarounds like this one, but it doesn't seem to work for our case. Is there any straightforward way to retrieve room information from rvt in Forge?

...

ANSWER

Answered 2017-May-23 at 07:51

Unfortunately room information is not exposed through the Forge translation at the moment. We have a change request pending about it because several developers have been asking this feature. It will be provided in the future but at the moment the best workaround is the link that you pointed out. Sorry for the bad news.
