Hello, I have been tasked with outlining some ideas for a database to store scientific image data. I am looking for suggestions for a server architexture database that will allow for scaling, high avaialbility and preformance. from what i read, it seems to be best practice to store urls or filepaths metadata in a db that point to the image. I was looking at using MongoDB, Postgresql or something similiar.

I am looking for suggestions, best practices, expirence etc.:

To summerize:

1. What are some recommended databases that preform well and are scable?

2. What is the best way to handle TB datasets of image data.

3. What is the best filetype to use (HDF5 vs TIFF vs something else?) in this scenario?

4. Are there any HW recommendations?

5. Lastly, ZFS? ext4/5? what type of filesystem is best for this?

Thanks.
