Is there a way to access a levelDB database from several programs? Is there some kind of option to open the dababase as read only?
For now, when opening the same database from to programs I get:
/path/to/dir/with/levelDBdatabase/LOCK: Resource temporarily unavailable
Cheers!
Unfortunately, LevelDB is designed that way and it doesn’t allow more than a single instance of the database to be open. All of the options are for a single process, but if you have multiple threads then you can get a snapshot and iterate over it in read-only mode (allowing other threads to read/write to the underlying database at the same time).
Do you want to achieve a specific behavior? If so, let us know what it is and we might be able to help.
