Well definitely google cloud spanner doesn’t offer any features related to COBOL — but it’s kind of hard to imagine that there are any projects which want to both (1) migrate away from mainframes (2) keep using COBOL. But if you’ve decided that your task of migrating away from the mainframe will involve porting a bunch of cobol transaction processing code into some other language ... seems you might be able to do relatively straightforward rewriting of this kind of logic into some language that creates google cloud spanner transactions ... At least much more straightforwardly than the kinds of rearchitecting required if you had to factor in how the logic would need to change to deal with weakening of the storage systems consistency model. You could be correct in suggesting that the main difficulty of migrating away from mainframes is the unfamaliarity of these codebases ... but what’s the next hardest part? And Google Cloud Spanner does offer ACID transactions ...
