SYSTEM AND METHOD FOR RARE COPY-ON-WRITE IN A DISTRIBUTED COMPUTING ENVIRONMENT

摘要

A distributed computing environment is provided with a system and method for supporting rare copy-on-write data access. The system operates a data structure in a read only pattern suitable for serving a plurality of read requests with reduced overhead. The system, upon receiving a write request, creates a copy of data to execute the write request. The system defers writing the mutated data back to the read-only data structure. The system thus allows for multiple mutations to be made to the copy of the data using a read/write access pattern. After a number of read-only requests are received, the mutated data is written back to the read-only data structure. A monitor counts read and write requests in order to reduce overall read/write overhead and enhance performance of the distributed data grid.

1. A method for supporting efficient data access in a distributed computing environment, the method comprising:
providing a data structure in the distributed computing environment; serving a plurality of read requests from the data structure; creating a copy of data from the data structure in response to a write request to modify said data; modifying said data in response to said write request; providing read/write access to said modified data; monitoring access to said modified data; writing said modified data back to said data structure after a threshold number of read requests have been received for said modified data.
