What is com LMAX Disruptor?
The LMAX Disruptor is a high performance inter-thread messaging library. It grew out of LMAX’s research into concurrency, performance and non-blocking algorithms and today forms a core part of their Exchange’s infrastructure.
What is a disruptor weapon?
A disruptor was a particularly powerful type of energy weapon often preferred by assassins and bounty hunters. Disruptor weapons were similar to their blasters counterparts in many ways, such as the use of blaster gas and energy cell. Popular forms of this weapon included the disruptor pistol and the disruptor rifle.
What is the disruptor?
a person or thing that prevents something, especially a system, process, or event, from continuing as usual or as expected: endocrine/hormone disruptors.
How is the size of the ring buffer defined in disruptor?
In the constructor of Disruptor, the following are defined: Event Factory – Responsible for generating objects which will be stored in ring buffer during initialization The size of Ring Buffer – We have defined 16 as the size of the ring buffer. It has to be a power of 2 else it would throw an exception while initialization.
What kind of data structure does a disruptor have?
Disruptor has an array based circular data structure (ring buffer). It is an array that has a pointer to next available slot. It is filled with pre-allocated transfer objects. Producers and consumers perform writing and reading of data to the ring without locking or contention.
How big of a ring buffer do I need for publishevent?
Specify the size of the ring buffer, must be power of 2. Get the ring buffer from the Disruptor to be used for publishing. Notice that the lambda used for publishEvent () only refers to the parameters that are passed in.
What is the purpose of the Disruptor library?
The Disruptor is a library that provides a concurrent ring buffer data structure. It is designed to provide a low-latency, high-throughput work queue in asynchronous event processing architectures. To understand the benefits of the Disruptor we can compare it to something well understood and quite similar in purpose.
