lineárizálható

Lineárisálható, a Hungarian word for "linearizable," is a term used in computer science, particularly in the context of concurrent data structures and distributed systems. It refers to the property of an operation or a sequence of operations that can be transformed into a linear sequence of operations, preserving the real-time order of non-concurrent operations.

In simpler terms, a data structure or system is linearizable if, from an external observer's perspective, the operations appear to take effect instantaneously at some point within their real-time duration. This property is crucial for ensuring that concurrent operations behave as if they were executed sequentially, which is essential for maintaining consistency and correctness in distributed systems.

Linearizability is a stronger guarantee than sequential consistency, as it not only ensures that the operations appear to be executed in some sequential order but also that this order respects the real-time order of non-concurrent operations. This makes linearizability a valuable property for systems where the order of operations is critical, such as in databases and distributed file systems.

Achieving linearizability can be challenging, especially in the presence of failures and network partitions. However, various algorithms and techniques, such as consensus protocols and quorum-based systems, have been developed to ensure linearizability in distributed systems. These methods often involve coordination among multiple nodes to ensure that operations are executed in a consistent and ordered manner.
