2021-06-09	exp: Use LocalOutputFile for Parquet writers	Fabian Mastenbroek
	This change updates the Parquet writers used in the Capelin experiments to use our OutputFile implementation for local files, to reduce our dependency on Apache Hadoop.
2021-06-09	exp: Use LocalInputFile for Parquet readers	Fabian Mastenbroek
	This change updates the Parquet readers used in the Capelin experiments to use our InputFile implementation for local files, to reduce our dependency on Apache Hadoop.
2021-06-02	simulator: Add uniform interface for resource metrics	Fabian Mastenbroek
	This change adds a new interface to the resources library for accessing metrics of resources such as work, demand and overcommitted work. With this change, we do not need an implementation specific listener interface in SimResourceSwitchMaxMin anymore. Another benefit of this approach is that updates will be scheduled more efficiently and progress will only be reported once the system has reached a steady-state for that timestamp.
2021-06-01	simulator: Centralize resource logic in SimResourceInterpreter	Fabian Mastenbroek
	This change introduces the SimResourceInterpreter which centralizes the logic for scheduling and interpreting the communication between resource consumer and provider. This approach offers better performance due to avoiding invalidating the state of the resource context when not necessary. Benchmarks show in the best case a 5x performance improvement and at worst a 2x improvement.
2021-05-18	chore: Address deprecations due to Kotlin 1.5	Fabian Mastenbroek
	This change addresses the deprecations that were caused by the migration to Kotlin 1.5.
2021-05-05	exp: Add support for experiment configuration	Fabian Mastenbroek
	This change adds support for configuring the experiments via configuration files using the TypeSafe config library. In the future, we will also integrate support for configuration into the harness.
2021-05-04	exp: Fix aggregation of power draw	Fabian Mastenbroek
	This change fixes the aggregation of the power draw metric. Previously, if the power draw did not change between collection cycles, the power draw would be reported as zero. This change uses OpenTelemetry Views to collect the latest value of the power draw each cycle.
2021-04-25	build: Migrate to flat project structure	Fabian Mastenbroek
	This change updates the project structure to become flattened. Previously, the simulator, frontend and API each lived into their own directory. With this change, all modules of the project live in the top-level directory of the repository. This should improve discoverability of modules of the project.
