git seems to have embedded key-value #metadata annotation capabilities... 😻 #AHAlodeck ahoi!

https://github.com/ArkThis/AHAlodeck/blob/main/res/0byte-db_entry.png

Right-click-edit-metadata happily in-use over 1 year now: Amazing!

so **each** key/value-pair of #metadata can be about 64kB.

This is sufficient to hold most annotations stored as #EmbeddedMetadata currently present in most file formats.
(eg #mp3, #mp4, #iptc, #tiff, #jpg, etc)

But from then on, the file-format becomes irrelevant for this task!

Very helpful insights on "how much actual bytes" can be stored in #xattrs on `btrfs`:

https://github.com/kdave/btrfs-progs/issues/917

Current limit = about the nodesize (it was formatted with).

nodesize - sizeof(struct btrfs_header) - sizeof(struct btrfs_item) - sizeof(btrfs_dir_item)

Current default = 16K - 101 - 25 - 30 , which is 16228 bytes

Maximum (for now) is ~64kB, if formatted like this:

`$ mkfs.btrfs -n 64K /dev/sdX`

#VectorFS: "transforms your Linux filesystem into a vector database by leveraging the native VFS (Virtual File System) extended attributes."

This proofs my design to offload /many/ #database functionality onto the filesystems is a working way to go.

*nice* 😌 🛋️ #AHAlodeck

"Link local files, reference data seamlessly, and manage your personal knowledge with just your file browser – all open-source and integrated into your filesystem."

Sounds familiar?

No this is not my #AHAlodeck, but I'm very happy someone has the same ideas - and even happier that we're now in contact with each other! 🥳

Very interesting. It confirms my observations and research on #AHAlodeck:

It's time we allow ourselves to do-digital-data differently. #GLAM #DLTP #Archiving

Highlighting the necessity and benefits of "data-centric" design paradigms, rather than application-focused ones.

Oh, I'm loving this!

I'm not alone! 🥳

Yes! It's time to offload meta+data issues to the filesystem. A common, standard ground - and scale with hardware - not #EternalMigration neverending human-hours...

Me engaging on #Smbd ("Samba") mailing lists about support for "larger" (eg 64kB) key/value attributes on filesystem level (#xattrs):

Good news! 🥳

Reading a "History of Graph Databases" article on #redis:

Having worked with mostly SQL and table data, I feel like entering a new era of data handling!
