It defines a lookup server, two database servers and three clients and checks the database integrity and the validity of the client operations. Even then, it cannot be sure that the thread trying to add a new socket channel to the selector will get the chance to do so before the main thread blocks on the select method again. A blocking socket, as the name says, will block when sending or receiving a message. An important problem I should mention here involves the use of the selector (when using nonblocking sockets). #opensource.

A new distributed web protocol for smart contracts and decentralized applications. Each request received will be assigned to a thread in the pool, if one is available; it will wait for an available one otherwise. git ;-). First it will connect to a database server, which will assign it a unique TID (transaction id). Most importantly when using a selector, the main thread will block on the select method so no one else could add a new socket channel to the selector until an incoming connection releases it. The DatabaseObject class defines an object stored on a database server. #opensource. FoundationDB - the open source, distributed, transactional key-value store. That's where technical writing and documentation come in.
