Blind write

Last updated

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, if a read r(X) of a resource X does not occur before a write w(X) to that resource in a transaction, then w(X) is blind write.[ citation needed ]

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]
