I got a new project, with 100 user in Europe. In this case, I need to handle production and sales processes an its documentations in PostgreSQL with PHP. The load of the sales process is negligible, but every user produces 2 transaction in the production process, with 10-30 scanned documents (each are 400kb - 800kb), and 30-50 high resolution pictures (each are 3-8 MB), and they wanted to upload it to 'somewhere'. 'Somewhere' could be the server files system, and a link in the PostgreSQL database for the location of the files (with some metadata), or it could be the PostgreSQL database.
My question is that: what is your opinion about to store the scanned documentation and the pictures in the database? This is a huge amount of data (between daily 188MB and 800MB data, average year is about 1 TB data), but is must be searchable, and any document must be retrieved within 1 hour. Every documentations must be stored for up to 5 years... It means the database could be about 6-7 TB large after 5 years, and then we can start to archive documents. Any other data size is negligible.
If you suggest, to store all of the data in PostgreSQL, what is your recommendation about table, index structure, clustering, archiving?
Thank you in advance!
Regards,
Carl
