Google patents system to manage database updates under heavy load
Google has been granted a patent for a method that manages how a distributed database records changes. The system monitors the volume of incoming data requests and starts extra recording processes if the load gets too high. Once the load decreases, it stops the extra processes and combines their records into a single, consistent history.
In the filing’s own words
A method includes executing an initial instance of a change log process for a distributed system, each instance of the change log process configured to store a transaction history of transactions executed on the distributed system. The method also includes receiving transaction requests for executing corresponding transactions on the distributed system and determining a change log load based on the received transaction requests. The method includes executing at least one subsequent instance of the change log process when the change log load satisfied a threshold load. When multiple instances of the change log process are executing, the method includes ceasing execution of the at least one subsequent instance of the change log process and merging the transaction history of the initial instance of the change log process and the transaction history of the at least one subsequent instance of the change log process.
What exactly they claim (claim 1)
1. A computer-implemented method executed by data processing hardware that causes the data processing hardware to perform operations comprising: executing a plurality of instances of a change log process for a distributed system, each instance of the change log process configured to store a respective transaction history of transactions executed on the distributed system; receiving transaction requests for executing corresponding transactions on the distributed system; determining a change log load based on a number of received transaction requests; allocating the transaction requests to the plurality of instances of the change log process based on the change log load; and merging the respective transaction history of each of the plurality of instances of the change log process.
