Greetings,
I have some large files (larger than a few gigs) that I need to keep on this, and I'm using postgres to manage metadata about these files.
My concern is making sure that the metadata and file stay in sync and as far as I can see, introducing transactional support to file + db operations requires another software layer that gives me a transaction manager that I can (hopefully) use to keep metadata and file updates in sync.
I've been thinking about moving file modification code to postgres functions and wrapping the whole transaction mechanism using postgres transactions. Just a high level idea, but I wanted to ask for your input before looking into it. Is it too stupid to attempt to use postgres's functions as a transaction manager for file operations and db updates?
I'm going to make calls for metadata update to db anyway, and my updates to large files is incremental and small in nature. So I thought why don't I get rid of a higher level transaction layer and do it all from a function in postgres?
Other than my probably stupid idea, your advice to manage this setup would be much appreciated.
