This commit optimizes session attribute saving by ensuring batch updates are used whenever possible. To make this possible, delta now tracks operations for each attribute change in order to be able to deduce SQL operation. Additionally, if there is only a single attribute change, regular update is executed rather than batch operation. Closes gh-1051
= Spring Session image:https://travis-ci.org/spring-projects/spring-session.svg?branch=master["Build Status", link="https://travis-ci.org/spring-projects/spring-session"] image:https://badges.gitter.im/spring-projects/spring-session.svg[link="https://gitter.im/spring-projects/spring-session?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge"] Spring Session provides an API and implementations for managing a user's session information, while also making it trivial to support clustered sessions without being tied to an application container specific solution. It also provides transparent integration with: * `HttpSession` - allows replacing the `HttpSession` in an application container (i.e. Tomcat) neutral way, with support for providing session IDs in headers to work with RESTful APIs. * `WebSocket` - provides the ability to keep the `HttpSession` alive when receiving WebSocket messages * `WebSession` - allows replacing the Spring WebFlux's `WebSession` in an application container neutral way. == Modules Spring Session consists of the following modules: * Spring Session Core - provides core Spring Session functionalities and APIs * Spring Session Data Redis - provides `SessionRepository` and `ReactiveSessionRepository` implementation backed by Redis and configuration support * Spring Session JDBC - provides `SessionRepository` implementation backed by a relational database and configuration support * Spring Session Hazelcast - provides `SessionRepository` implementation backed by Hazelcast and configuration support == Code of Conduct This project adheres to the Contributor Covenant link:CODE_OF_CONDUCT.adoc[code of conduct].
