Abstract:
A method for logging changes to data stored in a distributed data storage system can include responding to a request to change the data stored in the distributed data storage system by generating a log entry corresponding to the change. A replica of the data can be stored at each of a first computing node and a second computing node comprising the distributed data storage system. The log entry can be added to a first log stored at the first computing node and propagated to the second computing node to add the first log entry to a second log stored at the second computing node. A crash recovery can be performed at the first computing node and/or the second computing node based on the first log and/or the second log. Related systems and articles of manufacture, including computer program products, are also provided.
