This Windows only embedded engine has long been part of Microsoft Exchange and Active Directory servers. The API was public but not well documented. Berkeley DB was a quality cross-platform alternative but I suspect that some permutation of RocksDB now dominates this use case.
It should be noted that local SQL Server using fast IPC communication is quite good and rumors of Microsoft Exchange replacing ESE with SQL Server have popped up many times over the years.
