2022-10-03feat(exp/base): Add provisioning tool for experimentsFabian Mastenbroek
This change adds to the experiment base in OpenDC a provisioning tool to help setup the experimental environment in a reproducible manner. The experimental environment can be defined in terms of *provisioning steps* which manage the allocation, configuration, and clean-up of all resources necessary for the experiments. The provisioning steps are executed sequentially, so in case of dependencies, the steps need to be ordered correctly.
2022-08-03build: Update simulator dependenciesFabian Mastenbroek
This change updates the simulator dependencies to the latest available version where possible.
2022-08-03build: Update to Gradle 7.5Fabian Mastenbroek
This change updates the build system Gradle to version 7.5, which ships Kotlin 1.6.21. That is the same version currently used by OpenDC and should reduce the warning messages produced by Gradle due to version mismatches.
2022-08-03build: Update to Quarkus 2.11.1Fabian Mastenbroek
This change updates Quarkus to version 2.11.1 which fixes an issue with the Gradle development mode where the working directory was incorrect. This meant that the traces failed to be loaded.

2022-05-15build(web/api): Ensure Node.js is downloadedFabian Mastenbroek
This change updates the build configuration in order to ensure that Node.js is downloaded onto the build system. This drops an explicit dependency on a system installation of Node.js and allows us to ensure that the project is built against the correct Node.js version.
2022-05-06refactor(harness): Remove OpenDC Harness modulesFabian Mastenbroek
This change removes the OpenDC Harness modules from the main repository. We have made the decision to take a different direction regarding the specification and execution of experiments. The design of the current harness does not integrate well with the specification of experiments in the web interface. The new version focuses on proper integration with the web interface, as well as via the command line interface.
2022-05-06refactor(telemetry): Remove dependency on OpenTelemetry SDKFabian Mastenbroek
This change removes the dependency on the OpenTelemetry SDK. Instead, we'll only expose metrics via the OpenTelemetry API in the future via adapter classes.
2022-05-02refactor(trace/parquet): Drop dependency on AvroFabian Mastenbroek
This change updates the Parquet support library in OpenDC to not rely on Avro, but instead interface directly with Parquet's reading and writing functionality, providing less overhead.
2022-04-30feat(trace/tools): Add support for querying traces using SQLFabian Mastenbroek

2022-04-30feat(trace/calcite): Add Calcite (SQL) integrationFabian Mastenbroek
This change adds support for querying workload trace formats implemented using the OpenDC API through Apache Calcite. This allows users to write SQL queries to explore the workload traces.
2022-04-24build: Update to Jandex Gradle 0.12.0Fabian Mastenbroek
This change updates the Jandex Gradle plugin to version 0.12.0. This version addresses some deprecation warnings reported by Gradle for the future 8.0 release.
2022-04-21build(web/api): Update to Quarkus 2.8.1.FinalFabian Mastenbroek
This change updates the web API to use Quarkus 2.8.1.Final. This release fixes an issue we had with local extensions failing to build due to some build directories missing.
2022-04-21build: Update to Kotlin 1.6.21Fabian Mastenbroek

2022-04-05build: Update dependency versionsFabian Mastenbroek
2022-04-05build: Update to Kotlin 1.6.20Fabian Mastenbroek
2022-04-05build: Update to Gradle 7.4.2Fabian Mastenbroek
2022-04-04refactor(web/runner): Update runner to use new web clientFabian Mastenbroek
This change updates the web runner implementation to use the new API client introduced in the previous commit.
2022-04-04fix(web/api): Support dynamic JSON type selection for DBFabian Mastenbroek
This change adds support for dynamically selecting the appropriate JSON type for the current database. For Postgres, this will be the JSONB type, while for H2 this is either the BLOB or JSON type.
2022-04-04feat(web/api): Initial API implementation in KotlinFabian Mastenbroek
This change adds the initial implementation of the new API server in Kotlin, replacing the old API written in Python. The implementation uses Quarkus, RESTEasy, and Hibernate to implement the new API endpoints. The reason for replacing the old API server is unifying the build and deployment toolchains, reducing the number of technologies necessary to work with OpenDC. Furthermore, we envision bundling the entire OpenDC project into a single distributions, allowing users to launch their own deployment trivially.
2022-04-04feat(web/proto): Design unified communication protocolFabian Mastenbroek
This change adds a unified communication protocol in form of the module opendc-web-proto which contains the classes that form the communication protocol of OpenDC's API v2. By having the protocol in a separate module, we can utilize the classes in both server and client.
2022-04-04build: Move build dependencies into version catalogFabian Mastenbroek
