Limit on number of keys

We are using rocksdb (via its JNI in a java application).

What is the maximum number of keys that can be supported?

I’m debugging an issue where rocksdb.estimate-num-keys property seems to be overflowing for a 4byte signed integer.

there’s no limit as far as i know to the number of keys RocksDB can support but the rocksdb.estimate-num-keys property returns an unsigned 8 byte value for all the keys in the requested CF.
