Hey, I have been tinkering with adding a replay system to my game so people can study positions, do branching, share things, etc. but so far I just have the 'offline' implementation that is totally clientside, and the replay is saved as a giant String of raw data which the client can parse through into a series of moves. I think the obvious final version of this would involve some serverside aspects that have a more multiplayer-centric behavior, such as displaying latest high rank games on title screen, or having some replays attached to people's account.
To do this, it would simplify things to just save that string into BigDB, but there are edge cases where a game could go on for 100+ turns, making the raw data string 1000+ characters long, and I can't find anywhere if there is some maximum string size in BigDB? I think I remember each object having 500kb allocated to it, which would be plenty, but wondering if stacking a chunk of that into a single string would be ok??
