NET Core 3. I want to be able to upload large files to server like 2Gb of file size or even more and download them after that and want to do it without having future problems with memory overflowing and everything.
If you have files that large, never use byte[] or MemoryStream in your code. In this example, we stream the entire file to another service. In some cases, it would be better to save the file temporarily to the disk. Sometimes the issue is that we used Nginx as a front proxy to our asp. This is exactly what in my case as I tried to debug in docker or.
The problem is you have to deal with long files wherever you will consume them you need high resources in order to read.
One possible solution is to divide the file on the basis of information into different chunks or process it in a separate job or thread or use parallelism in. Upload Large Files. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

You can read how to use this standard in the Tabular data standard profile.
RFC aims to reduce common problems and help with data management. The standard and this guidance focus on the manual process and do not refer to using automated tools, libraries and languages. You can use some of the principles in this document in automated environments. When creating a CSV file you should consider the needs of government users such as statisticians, data collection agencies, developers and data engineers. You should also consider whether your CSV will be read by machines or by humans, and understand how this affects the accessibility needs of your file.
Before you produce a CSV file, make sure the data is about one subject area. Your columns should relate to each other and not mix unrelated information. For example, you should not put employee records and budget figures in the same CSV file.
For the Bucket parameter, we'll use our bucket name, whereas for the Key parameter we'll add the file name we want to save as, and for the Body parameter, we'll use fileContent.
You can replace "cat. If every thing is fine, you should see output like what is shown below with a link to your file, which is stored in data. Location :. Additionally, you can go to your bucket in the AWS Management Console and make sure the file is uploaded. To offload our application servers, a popular choice of developers is to host files using storage providers such as AWS S3, Google Cloud Storage, etc.
