2022-10-06style: Eliminate use of wildcard importsFabian Mastenbroek
This change updates the repository to remove the use of wildcard imports everywhere. Wildcard imports are not allowed by default by Ktlint as well as Google's Java style guide.
2022-06-07refactor(trace/api): Introduce type system for trace APIFabian Mastenbroek
This change updates the trace API by introducing a limited type system for the table columns. Previously, the table columns could have any possible type representable by the JVM. With this change, we limit the available types to a small type system.
2022-05-02feat(trace/api): Add support for projecting tablesFabian Mastenbroek
This change adds support for projecting certain columns of a table. This enables faster reading for tables with high number of columns. Currently, we support projection in the Parquet-based workload formats. Other formats are text-based and will probably not benefit much from projection.
2021-09-21feat(trace): Add support for writing tracesFabian Mastenbroek
This change adds a new API for writing traces in a trace format. Currently, writing is only supported by the OpenDC VM format, but over time the other formats will also have support for writing added.
2021-09-20refactor(trace): Simplify TraceFormat SPI interfaceFabian Mastenbroek
