QUESTION
I am trying to stream data from a large csv file into readline. I tried just piping the readStream from s3 into the readline input, however I faced an error with S3 only allowing a connection to stay open for a certain amount of time.
I am creating the stream from s3 like so:
...ANSWER
Answered 2022-Jan-07 at 18:01I was able to work in a solution for this using the AWS S3 Range
property and creating a custom readable stream with NodeJS Stream API.
By using this "smart stream" I was able to grab data in chunks in separate requests to the S3 instance. By grabbing the data in chunks, I avoided any timeout errors as well as creating a more efficient stream. The NodeJS Readable Super class handles the buffer so as to not overload the input to readline. It also automatically handles the pausing and resuming of the stream.
This class made it possible to stream large files from AWS S3 very easily:

...ANSWER
Answered 2021-Dec-19 at 19:28You need to use StreamReader class. It is not necessary to read all file content into RAM. Open one StreamReader and one StreamWriter. Reed file line by line and write translated data into a temporary file. When all content is translated just move temp file to needed destination. Don't forget to close source and destination handles before moving.

I recently upgraded my Tomcat 6 to 9.0.52 by referring to https://blogs.nologin.es/rickyepoderi/index.php?/archives/44-Tomcat-7-and-the-Invoker-Servlet.html
The project is deployed successfully on my local machine however, and I am trying to deploy my project to a remote server but my tomcat throws 'HTTP Status 404 – Not Found' error whenever I try to deploy using a WAR file.

QUESTION
I have a text file with names, each name is on a different line. I want to set the first line to a variable, then after 3 seconds, take the second line and set it to the same variable and so forth. Something like a for loop will probably try to be used. I am using Node Js, and can use packages and others code etc, just need a way to get this done. Additionally I can set the text files contents to a string, so if there is no way to sort through the text file I can use a string no problem. I just need a way to go through the lines and set each to a variable (const, var, etc).
Test.txt example:
Kevin
Bob
Sally
Darla
John
Kim
Then what I want to do is set line 1: Kevin to a string. const name = Kevin; Then 3 seconds later set it to Bob etc etc.
Thanks in advance!

Install LineReader
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
