Staying in Sync: from Transactions to Streams
"Martin Kleppmann explores using event streams and Kafka for keeping data in sync across heterogeneous systems, and compares this approach to distributed transactions, discussing what consistency guarantees can it offer, and how it fares in the face of failure."

Unison File Synchronizer
"Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other."

JSR 133 (Java Memory Model) FAQ
Many people assumed that the use of the volatile keyword would eliminate the problems that arise when trying to use the double-checked-locking pattern. In JVMs prior to 1.5, volatile would not ensure that it worked (your mileage may vary). Under the new memory model, making the instance field volatile will "fix" the problems with double-checked locking, because then there will be a happens-before relationship between the initialization of the Something by the constructing thread and the return of its value by the thread that reads it.

The JSR-133 Cookbook
waiting loads or speculatively executed instructions. These effects may lead to further interaction among caches, main memory and other processors. But there is nothing in the JMM that mandates any particular form of communication across processors so long as stores eventually become globally performed; i.e., visible across all processors, and that loads retrieve them when they are visible.
