At the same time, the volatile visibility guarantee ensures that the consumer will always see the latest value of writeSequence. In the offer method, a write to the volatile field writeSequence guarantees that the writes to the buffer happen before updating the sequence. We can make the ring buffer concurrent and lock-free in this case by making the sequence fields volatile: private volatile int writeSequence = -1, readSequence = 0 So, the backing array is contention-free and we can get away without any synchronization.īut we still need to ensure that the consumer can see the latest value of the writeSequence field ( visibility) and that the writeSequence is not updated before the data is actually available in the buffer ( ordering).
The producer writes data to the buffer and increments the writeSequence, while the consumer only reads from the buffer and increments the readSequence. Let’s make it thread-safe for the simple single-producer and single-consumer case. Our implementation of the ring buffer is not thread-safe.
