Answered 2022-Apr-02 at 15:59In step 2, instead of using the topic cdc_window_table, I should use something like _confluent-ksql-xxx-ksqlquery_CTAS_CDC_WINDOW_TABLE_271-Aggregate-GroupBy-repartition.
This table's changelog topic is automatically created by KSQL when I created the previous table.

QUESTION
I am doing a POST request to an uri, which returns me a stream of JSON data. This is done in a separate thread that is created at program start. If it matters, this is part of a Unity project. My code looks like this:
...ANSWER
Answered 2022-Apr-02 at 04:09This is a known problem with many of the async IO methods that they do not support cancellation or timeouts. What I do to get around it is to close the stream object you're reading from, which will cause an exception. It's not very elegant and it won't scale great if you see yourself cancelling a lot of read operations, but it works fine.
Here's a very simple example that illustrates the concept. The particulars will change a bit depending on the underlying object you're using if it's some sort of Stream or a network client.

I want to implement a reconnect logic to the https://pub.dev/packages/flutter_client_sse package. The http connection stays open and listens to server side events. When the connection is lost for some reason the client should try to reconnect. An exception is thrown as soon as the connection is lost but I'm not able to catch it.
Code for building the connection:

Answered 2022-Mar-04 at 22:01You need to await the response in try catch blocks to catch http errors,

QUESTION
Suppose I have a real-time stock quote streaming service, which has an endpoint that returns a Flux. This is real-time streaming data, and it has content-type of text/event-stream.
I want to create a service that subscribes to this data, and performs aggregate operations on groups of Quotes, such as the total volume, high, and low over the time period. These groups will be grouped by time. I also want this to be a real-time stream, which returns a summary of the quotes received per unit time, as each time period elapses.
My question is how do I do this? I've tried using Flux::groupBy and Flux::collectList or similar, but this waits for the stream to complete before emitting aggregate results for each time block. In a continuous stream of quotes, this will result in my service never emitting anything.
ANSWER
Answered 2022-Jan-17 at 18:15I was able to solve this problem by subscribing to the Flux stream from the streaming service, and then publishing to a Sink. Like this:

QUESTION
I'm writing a script in Google Sheets to retrieve a value from an API. The API provides text/event-stream responses ~every 10 seconds. Is there a way I can retrieve a single response without using async functions or event listeners? I'm not very competent in JavaScript, but because I'm working in Google Sheets, it seems like async functions and event listeners won't work properly. From what I've learned so far, the only way to work with text/event-stream responses is to use EventSource but I can't make it work with Google Sheets.
My goal is just to retrieve one response from the endpoint though, so any way I can accomplish that in Google Sheets would be great. Here is the endpoint in case that helps:
Because I was unable to use EventStream in Google Sheets, I tried using a polyfil found here: https://github.com/amvtek/EventSource/blob/master/dist/eventsource.js
and then running it with:
...ANSWER
Answered 2021-Oct-21 at 06:06I believe your goal is as follows.
- You want to retrieve the 1st values from the URL of
https://pool.rplant.xyz/api2/poolminer2x/raptoreum/RThRfoQJg8qsoStLk7QdThQGmpbFUCtvnk/UlRoUmZvUUpnOHFzb1N0TGs3UWRUaFFHbXBiRlVDdHZua3x4using Google Apps Script and want to use the retrieved values at Google Spreadsheet.
When I saw https://github.com/amvtek/EventSource/blob/master/dist/eventsource.js, it seems that the request is run with XMLHttpRequest. At Google Apps Script, UrlFetchApp is used, and XMLHttpRequest cannot be used. I thought that this might be the reason for your current issue. But unfortunately, in the current stage, this cannot use text/event-stream type at Google Apps Script. When your URL is requested with UrlFetchApp, it looks like the infinite loop. This is the current situation.
So, from My goal is just to retrieve one response from the endpoint though, so any way I can accomplish that in Google Sheets would be great. and the above situation, I would like to propose a workaround. When you are running your script on Google Spreadsheet, how about retrieving the value from the URL using Javascript? Google Apps Script can retrieve the values from Javascript side using a dialog and a sidebar. From your question, when Javascript is used, the value can be retrieved. I thought that this might be able to be used. When this workaround is reflected in the Google Apps Script, it is as follows.
Code.gs
Please copy and paste the following script to the script file of the script editor of Google Spreadsheet.
