Abstract
An improved approach is described for implementing transformations of data records in high concurrency environments. Each transformation is performed in parallel at the source when the data record is first generated. According to one approach for data integrity validation, record generators compute an integrity checksum for a newly generated record before copying into a data unit in shared memory. Subsequent generators may aggregate integrity checksums for data records into checksums for data units incrementally. This approach achieves end-to-end protection of data records against corruption using an efficient method of maintaining verifiable data integrity. In another approach, compression and encryption data transformations may be performed by themselves, or in combination with an integrity checksum transformation.
