This paper compares static and dynamic SAGAs, models for long-running transactions, by extending both to handle nesting and analyzing their differences.

Contribution

It extends static and dynamic SAGAs to include nesting and provides a comparative analysis of the two approaches.

Findings

Extended static SAGAs with nesting capabilities.

Extended dynamic SAGAs with nesting capabilities.

Provided a detailed comparison of static and dynamic SAGAs.

Abstract

SAGAs calculi (or simply SAGAs) have been proposed by Bruni et al. as a model for long-running transactions. The approach therein can be considered static, while a dynamic approach has been proposed by Lanese and Zavattaro. In this paper we first extend both static SAGAs (in the centralized interruption policy) and dynamic SAGAs to deal with nesting, then we compare the two approaches.
