I both key max size and value max size. There is some cookbook recipe for handling that case: https://apple.github.io/foundationdb/blob-java.html but in my case it is an extra indirection and I don't need that petabytes scale, yet.
Also look at the *known* limitations https://apple.github.io/foundationdb/known-limitations.html To be fair, there is a new storage engine that is in the work, that should remove some of those limitations, but not ETA yet. I will continue to experiment with WiredTiger. Even if I also hit some limits related to the fact that I try to store many small bytes 20 000 keys of 150 bytes which leads the database engine to deadlock during the transaction. I tried the same workload on leveldb using hoply <https://github.com/amirouche/hoply/> it loads 14G without crashing. But LevelDB does not support transactions. I know, I know that transactions are not required all the time but I prefer to be ready for the case where it is required. Another solution is to use rocksdb which is a fork of leveldb with support for transactions.
