Depending on the amount of data to process, file generation may take longer.

If it takes too long to generate, you can limit the data by, for example, reducing the range of years.

Abstract

EN The requirements in terms of reliability and availability have become crucial in the context of many modern information systems. Therefore, fault-tolerance support in these systems becomes pivotal. Among possible techniques used to increase fault-tolerance are checkpointing and message logging. Both, checkpoint and message log, are commonly said to be saved in a stable storage, which is an abstraction of a perfect storage, that survives failures, and thus ensures the stability of recovery data. In this paper, we propose to implement a stable storage abstraction by replicating logs that contain recovery information. For this purpose, we introduce the eager request replication protocol, and discuss its functioning in case a failure of any system component occurs. The proposed solution is especially tailored for the service oriented systems, though it is not limited to them.
