Abstract: Is JDataStore Multi-User, Multi-Threaded?
JDataStore is multi-user and multi-threaded when used in the same process.
To use it multi-user in separate processes, start the JDataStore server and use the remote JDataStore JDBC driver to connect.
The store should be "served" by the DataStore Server (Tools | DataStore Server). You can connect to it using the RemoteConnection driver. The server can also be launched standalone.
