RE: MySBDS - Steem Blockchain Data Service in MySQL
It is difficult and expensive to be working with such large databases which got me thinking about a way to potentially reduce the size of the database by more than 50% without too much of a sacrifice. Anyway, I noticed that the sbds_core_blocks table accounts for around two-thirds of the entire database size, and I'm guessing that the mediumtext entry named, "raw" (probably for raw blockchain data) probably accounts for the vast majority of that space, and it got me wondering if it might be possible to simply replace the "raw" entries with a single character or something save space. For example, I think doing this might enable the entire database to fit comfortably on a single $40/month droplet with room to spare.
I've been asking myself this exact same question as well, your approach just may work. I'll definitely post if I find some answers.
Another thing that may be worth considering is that the comments table is the second biggest in storage space, and it may be worthwhile to save space removing removing older edited versions of the "body" mediumtext entries. For example, sometimes I edit a big long post a few times to correct a few typos and this type of editing may be fairly common and may be able to reduce the database size a lot.
Yeah, great point! The
bodyis fully duplicated on edits so that really could save some significant space.
