Images compression and Its URLs

[elfin sequoia]

I noticed that Appwrite has a built-in compression algorithm for files. However, when I created a new file after creating the bucket and enabled the Zstd algorithm for compression, it did not change the file size. Is there a configuration I forgot to set? When does the compression start?
My second question is: there is a URL for the file in the bucket so, is there a way to get this URL from the SDK? Because the get_file method did not send this attribute.

Not sure about the compression, but for the url, you can dynamically build that pretty easily.

https://cloud.appwrite.io/v1/storage/buckets/AW_PROJECT_BUCKET_ID/files/IMAGE_ID/view?project=AW_PROJECT_ID

did you upload the file before or after making the compression algorithm change?

[elfin sequoia]

After....

My file's size on my desktop

The file's size on the storage

So, I understand that the compression starts immediately After I upload the file

[lunar jolt]

Compression happens on file upload

[elfin sequoia]

Does the compression algorithm support specific extensions or all MIME types?

[lunar jolt]

all types: https://github.com/appwrite/appwrite/blob/5cd94041dc1037f53f62d6afb78528021ece3fa1/app/controllers/api/storage.php#L542-L554

keep in mind, compressing something doesn't always make it smaller.

can you check the network logs for the get file request?

[elfin sequoia]

Sorry, I didn't understand what should I do?
You mean:

1. Do this request first storage.get_file(bucket_id, file_id)
2. Then do this command: docker compose logs appwrite --since 10m

[lunar jolt]

actually, i thought the file metadata would say whether it's compressed or not, but it doesn't. the database doesn't reflect it accurately either....

have you tried manually compressing with Zstd locally?

[dull veldt]

Is compression done to all files or files>30mb

[lunar jolt]

Files under 20MB

[elfin sequoia]

Hmmm, No I haven't

I am going to try it locally

[lunar jolt]

So the size here is the original size, not the compressed size

Can you look in the database, or the file on disk?

In the database, there should be a sizeActual column: https://github.com/appwrite/appwrite/blob/d86ee91316da92055442b6481469bc9550507303/app/controllers/api/storage.php#L603

[elfin sequoia]

Is there a specific path where the storage's files saved in on the desk?

[vestal drift]

I believe the files are in the appwrite_appwrite-uploads docker volume

[balmy loom]

I wanted to try this out and the compressed files size on disk is even larger than before uploading?

Disregard my last comment as I had encryption enabled for the bucket. But now with encryption disabled the files are still the same size (disk and console)

the original uploaded files are 2,1MB and 491KB so the compression doesn't seem to do much

[lunar jolt]

ya maybe the compression settings...
