Fed-agent – a Transparent ACID-Enabled Transactional Layer for Multidatabase Microservice Architectures

With the recent expansion of specialized databases and departure from the "one size fits all" paradigm, engineers might decide to use multiple databases. Each database holds a representation of a data object but offers transactions and consistency guarantees only locally. Existing solutions either require additional coding or do not provide global ACID transactions. In this paper, we present fed-agent, a transactional layer that provides global consistency and ACID transactions for single data objects within multidatabase systems. It requires no additional coding besides configuration files. We show that fed-agent scales linearly and introduces an overhead small enough for most microservice solutions.
