ASYNCHRONOUS REPLICATION IN A DISTRIBUTED STORAGE ENVIRONMENT

Title:

ASYNCHRONOUS REPLICATION IN A DISTRIBUTED STORAGE ENVIRONMENT

Document Type and Number:

WIPO Patent Application WO/2012/162173

Kind Code:

A3

Abstract:

Embodiments of the present invention relate to asynchronously replicating data in a distributed computing environment. To achieve asynchronous replication, data received at a primary data store may be annotated with information, such as an identifier of the data. The annotated data may then be communicated to a secondary data store, which may then write the data and annotated information to one or more logs for eventual replay and committal at the secondary data store. The primary data store may communicate an acknowledgment of success in committing the data at the primary data store as well as of success in writing the data to the secondary data store. Additional embodiments may include committing the data at the secondary data store in response to receiving an instruction that authorizes committal of data through a identifier.
