2022-02-18build: Remove opendc-platform moduleFabian Mastenbroek
This change removes the opendc-platform module from the project. This module represented a Java platform which was previously used for sharing a set of dependency versions between subprojects. However, with the version catalogue that was added by Gradle, we currently do not use the platform anymore.
2021-10-08perf(simulator): Optimize SimTraceWorkloadFabian Mastenbroek
This change improves the performance of the SimTraceWorkload class by changing the way trace fragments are read and processed by the CPU consumers.
2021-09-17refactor(telemetry): Create separate MeterProvider per service/hostFabian Mastenbroek
This change refactors the telemetry implementation by creating a separate MeterProvider per service or host. This means we have to keep track of multiple metric producers, but that we can attach resource information to each of the MeterProviders like we would in a real world scenario.
2021-08-24refactor(simulator): Execute traces based on timestampsFabian Mastenbroek
This change refactors the trace workload in the OpenDC simulator to track execute a fragment based on the fragment's timestamp. This makes sure that the trace is replayed identically to the original execution.
2021-08-13build: Update Kotlin dependenciesFabian Mastenbroek
This change updates the Kotlin dependencies used by OpenDC to their latest version.
2021-06-21simulator: Re-organize compute simulator moduleFabian Mastenbroek
This change re-organizes the classes of the compute simulator module to make a clearer distinction between the hardware, firmware and software interfaces in this module.
2021-06-17faas: Rename opendc-serverless to opendc-faasFabian Mastenbroek
This change renames the opendc-serverless module to opendc-faas to better distinguish between the two terms (Serverless and FaaS) and be clearer about the intent of the module. The opendc-faas module holds the code for the FaaS platform on top of OpenDC. Although this is one approach of doing serverless, serverless can also entail other services that will not be covered by this module.
2021-06-09build: Eliminate most Hadoop dependenciesFabian Mastenbroek
This change eliminates all Hadoop dependencies that are not necessary for Parquet to work correctly. As a result, the number of dependencies should now be greatly reduced, which in turn leads to less artifacts that need to be retrieved at build time.
2021-05-18build: Update to Kotlin 1.5.0Fabian Mastenbroek
2021-05-09serverless: Add support for custom termination policiesSoufiane Jounaid
This change adds support for custom termination policies for function instances. This allows the user to build different strategies for downscaling function instances after they become idle.
2021-05-07build: Use Gradle version catalogFabian Mastenbroek
This change adds support for the Gradle version catalog feature in our build configuration. This allows us to have a single file, gradle/libs.versions.toml, which contains all the dependency versions used in this project.
2021-05-06build: Prevent publishing application modulesFabian Mastenbroek
This change updates the Gradle build configuration so that the application modules (as opposed the libraries) are not published onto Maven Central.
2021-05-06build: Use type-safe project accessorsFabian Mastenbroek
This change updates the build scripts to use type-safe project accessors when specifying build dependencies between modules.
2021-05-05exp: Add support for experiment configurationFabian 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.
2021-05-05harness: Split harness into separate modulesFabian Mastenbroek
This change splits the OpenDC Experiment Harness into separate modules. This prevents users from pulling in unnecessary dependencies when depending on the harness API.
2021-04-25build: Migrate to flat project structureFabian 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.
