Blind write

From HandWiki
Short description: Computing term

In computing, a blind write, also known as a write-only transaction, occurs when a transaction writes a value without reading it.[1] In particular, a write wi(X) is said to be blind if it is not the last action of resource X and the following action on X is a write wj(X). Blind writes can cause anomalies if multiple different blind write transactions are executed at the same time.[2]

Any view serializable schedule that is not conflict serializable must contain a blind write.[3]
